Hi Folks,

After 2 years of running my E46ci with unoptimized 1JZGTE VVTI, i picked up an Edamage Blue which i had for several years to hook it up. As expected, used ECU always had problems, my ignition harness is not readable but the rest of it works fine. Initial runs started with 235 whp/ 315nm wtq at 5.2k RPM. A few more runs and we achieved 251 whp / 320 nm wtq at 5.1k RPM. I am not sure whether this is a healthy result of 1JZGTE VVTI, considering factory declared crank HP is at 276hp which i knew its underrated. Everything is stock except for intercooler pipes, air filter pipe, downpipe and exhaust.

It does drive much better and responsive than before, turbo spool much better and does not consume so much fuel i think. Still experimenting.

Next i will need to fix up the ignition timing on the ECU, get aftermarket FPR, boost controller, and increase the turbo to 1 bar. We should be seeing at 270 whp after that.

Cheers,
Ken

Give your car specs man. I'm curious to see how it was built
Hi man, its been a while, spec as below:

Engine:
Stock 1JZGTE VVTI
Custom 2.5" intercooler pipes
Forge Racing Intercooler
Custom downpipe
Custom mid section 2.5 pipe
24" straight flow resonator
12" straight flow mid muffler
FGK 3.0 Straight Flow Muffler
Apexi Cone Air Filter
Iridium IK20 spark plugs (came together with the engine, not sure how old it is)

Transmission
A340E Stock

ECU
1JZGTE VVTI stock ecu wired with Greddy Edamage Blue

All the above got me to 251 whp at 5.2k RPM. I think would be seeing 260 at 6.5k RPM as that's RPM cut off point.

I am pretty satisfy with what i have now but as mentioned, going to repair the ignition harness part, get a boost controller, FPR and i will tune on dyno again for 1 bar of boost on stock CT15B.

Cheers
Ken

Why do you keep calling it EDamage ?
Cause it does more damage than good in the wrong hands.

Where was the tuning done? Are they good?

250whp equates to about 310-320hp @ crank so that's a good number, especially at only 0.7 bar and you don't have much other mods. Btw 2jz in the US was factory rated at 320hp so 1jz by right should be lower.

Thank to Izso, i can't get Edamage out from my head.
Cause it does more damage than good in the wrong hands.

Done it at JC Racing despite some bad reviews, went ahead to test it myself and i was supervising the tuning all the way. I must say, they are pretty good, used about 1 hour to get it optimized when the wiring is done. They can't figure out how to wire up the ignition part though, they said its damaged but the other ECU repair guy i asked said it isn't. So who's correct i am not sure.

Damages your wallet.
Definitely but i got the Edamage for quite cheap so no complain so far.

250whp equates to about 310-320hp @ crank so that's a good number, especially at only 0.7 bar and you don't have much other mods. Btw 2jz in the US was factory rated at 320hp so 1jz by right should be lower.
Yeah with the traditional 4 speed auto gearbox, transmission lost at about 20%, i think its quite healthy, if i could adjust the ignition timing and increase the boost pressure to 1 bar, i should be seeing 270whp, but for now its fun enough to shred some tires. Next plan is to modify the mechatronic to make the hydraulic oil pressure higher for faster shift.

Cheers,
Ken

Ok but the whole modding endeavour is damaging to the wallet.
Definitely damaging but less damaged taken. I can still spend some for other mods. But first want to fix this Edamage (literally). Can anyone see if the below can be fixed ? I need my ignition timing back, JC Racing's Jacky said the circle area is the damaged or faulty area.

i recommend Repair ECU 1 Malaysia - Steven is pretty damn knowledgeable. But he's in Pahang now, no longer in Subang.

But hor... the reason why I call it eDamage is because of the number of fakes out there and the way the eManage mysteriously resets itself in some cases plus how it's not able to manage close loop, you're better off with a better ECU. What you using now that the eManage is out?

Save up for a proper Link or ECUMaster or MaxxEcu standalone la. The difference is night and day and the amount of money you pay to have it tuned is just a little more vs the Greddy.

He did ask me to send it over to his office in Pahang, Kuantan.

I am using emanage as none of the standalone i know of can control automatic gearbox, the ECU is cheap to get but wiring up and get it work "PERFECTLY" is so much harder compare to manual. Hence i try not to mess with original ECU, just need AFR and ignition timing tuned up will do. I am not aftering high HP, max i will go for 1.0 bar for stock CT15B turbocharger, we should be looking at 350 hp max at the flywheel. If you know any ECU that can control auto gearbox, let me know !

Thanks,
Ken

Agreed with your recommendation on Steven even i have never use his service but I did contact him on removing immobiliser from my Waja ECU. I like that he likes challenge and willing to work on my ECU.
What he did when repairing any electronic device is pretty simple but what he actually did is actually pretty damn hard.

Your last sentence made me straightaway google to find if such ECU exist. One of it is Maxxpro ecu. However after reading few lines of technical explanation...i am lost.hahahah. There is at least 2 more brand but it seems like they are designed to work with american make and model with capability to alter lock up point, shifting point and some other parameter.

Please update here if u manage to find such ECU and make it work. This is very interesting.

GunnerZ already pointed out the answer regarding the TCU control.

MaxxECU pro and some other models can control the Toyotal Axxx series of trannies


and not only MaxxECU, iirc the other brands can do the same. MaxxECU is just more open about it. Heck it can even control DCT, DSG and in theres the car with a rojak combination of the BMW ZF tranny being completely controlled by the MaxxECU pro paired with a 2JZ engine. Paddle shifter too. It's damn cool :


There's a full article from Paul Tan about this car too but I don't want to link it here in case they marah like they did last time with LY.

Anyway our cars nowadays are pretty much ancient so there's no such thing as "can't be done" with regards to our old tech stuff. The newer cars however is a different story.

MaxX Ecu Pro i knew about their capabilities to control AT and DSG gearbox, what i am worried is anyone locally "pro" enough to making them work properly or not. Another option is convert my ECU to manual, use standalone TCU to properly program the gearbox, i know one brand from South Africa, Diktator TCU can do this, we can adjust automatic shift points based on throttle opening by reading TPS sensor. It also allows adjustment to fluid pressure to increase bite of the clutches. Dude promised me plug and play of this unit, so i am keeping my options open to that.

Yup i knew about MaxX ECU Pro and their abilities to control Toyota A series gearbox. My issue is on the installer and tuner. MaxX will kill 2 birds with one stone if the tuner are very knowledgeable. At this moment, i think of swapping the stock ECU to manual type, and get another TCU to solely handle the gearbox is safer bet.

Thanks,
Ken

South Africa? I am very scared with South African brands now. Hahahaha...

As for MaxxEcu pros - I know a guy who can do it.

Care to elaborate ?

Oh ? Can this guy install a 5 speed A650E to My 1JZ as well ? Supposing the housing is the same and do not require modification, except for the output flange to driveshaft. If he can install the 5 speed gearbox, wiring up the ECU to both engine and gearbox, i am more than happy to get a full quote on the project.

Can't. I don't want to get in trouble with the local supplier who's known to be particular about these things.

Let me ask him and I'll back to you. What do you want to do specifically? I'll convey the message and let you know if it can be done.

Ok i respect that.

My 5 speed automatic project as below:

1.) Source a Toyota 35-50LS (A650E), chopped out from either Lexus LS 430, SC400, SC430, or Toyota Crown Majesta 4.0 (General year 2000-2004). These 5 models are known to have 1UZFE VVTI engine, the A650e from this era are improved to withstand higher torque rating from the V8.

2.) Mate the A650E to 1JZGTE VVTI, as far as i know the bellhousing is the same. We probably need to look into input and output flanges to make sure they mate perfectly

3.) Wire up the MaxX Pro ECU to both engine and gearbox. Setup the engine and transmission altogether.

I don't want to pay 2 different tuners in this project, so if your contact can do both hardware and software together, i am more than happy to get a quote.

Thanks,
Ken

Alternatively i have an odd idea, i know some 1JZ non turbo variant, especially those 1JZGE with VVTI, factory comes with the same Toyota A650e gearbox to drive small torque 1JZGE engine. I'd thought of using its ECU to control both 1JZGTE VVTI engine and the 5 speeder. Since i already have eManage, i will use eManage to intercept the 1JZGE ECU to control the turbo engine.

This idea is crazy but not necessarily workable. What's your guys opinion.

Basically the Edamage is controlling the engine but the tranny is still managed by the ECU right?
Its just like getting another TCU to handle gb without the tuning process of the TCU as engine already managed by Edamage. Sounds much simpler on paper.

I like the idea of a seperate TCU as i will have an interesting reading material here.

Yes that's what i meant, Edamage will control all the engine operations, while the transmission program in stock 1JZGE ECU still contolls the 5 speed. In theory it could work but whether will it fire up the engine or not, its another question, since the differences betweem 1JZGE and GTE is only the turbo.

My mech loves this kinda rojak jobs Hahaha... he replied almost instantly after I messaged him. He said "Are you sure MaxxECU Pro? That ECU alone is already RM12k"

Gulp... I said Mitevo got money no problem.

Then he said your rojak mashup is no problem and tuning the TCU with the ECU no problem but he needs to see what you have, whats enabled, whats missing etc before he can properly quote. Let me know if you wanna pay him a visit.

Walao eh dude, what do you mean by Mitevo got money no problem LOL. Well the ECU cost is within my expectation though but i still have to factor in the costs A650e, propeller shaft modifications to fit the gearbox, tuning and ETC, all together will be somewhere 16-17k.

My another option is use 2JZGE that has the 5 speeder gearbox ECU to control the gearbox, think your mech can help advise will this rojak works ?

He says advice is free. Just drop by chit chat and he'll oblige. Btw, he's only fluent in mandarin, canto and malay. Hope your language skills is there. Heheh...

Google Wai N Lin. Puchong Industrial.

Let me know when you go, maybe I can go there have a mini ZTH meetup

Don't worry i am multi lingual, mandarin is my first language. Ok perhaps after this week, bit busy running my own business while still under employment.

Perhaps we setup a date first for majority of us who can attend to feedback, i will go with mine:

1.) Mitevo7 - Ken, 17th Jan - 8 pm (Puchong Old Town White Coffee)

Dude, are you able convey my question of rojak 2JZGE 5 Speed Auto ECU to 1JZGTE VVTI to your friend ?
this rojak mix has been done countless times. No need to ask also I know it'll work. But that 2JZ TCU might need tweaking. Most of the autos that I've seen retain the 1JZ TCU.

In my case i would need the 2JZGE ECU to act as TCU that solely controls the 5 speed Auto, and i will be retaining 1JZGTE ECU + Greddy Emanage to control the engine, this rojak seems very complicated LOL

In my case i would need the 2JZGE ECU to act as TCU that solely controls the 5 speed Auto, and i will be retaining 1JZGTE ECU + Greddy Emanage to control the engine, this rojak seems very complicated LOL
Mech says meet him up at his place and he'll explain everything you need to know. Too much to type and ask like this. But the rojak like you suggested won't work

Had little issue recently, after the remap, my car's first gear is slipping alittle when go WOT. If i don't go WOT when launching, and only going WOT after shifted to 2nd gear, the transmission will not slip. Any tuning advise to reduce the slippage before recommending me to modify the auto gearbox ?

Considering this is your 1jz, it's pretty much stock right? If it's slipping there's something wrong with your GB if you ask me. Have you checked your oil? Are you using the right oil?

I'd personally try a proper GB flush first and fill with good quality oil and try again.

Oil just changed last 6000 km's ago with fresh filter. Using Addinol ATF cause that's the brand that my buddy mechanic is carrying. It drives OK before remapped, WOT before that won't slip or anything. Probably the ATF is too thin or anything ... might try to use original Toyota ATF meant for A340e and try it again.

Even if a change in oil fixes, bear in mind it's only temporary. Slipping only means the current GB has gone beyond it's limit. Could be due to age/wear.

Dont WOT anymore. Slipping is a sign of an impending bad event.

Assuming your 1jz came from the soarer and not the old supra (which is the same anyway), it should be on a Dexron III/IV oil.

And like what Parakeet said - if it's slipping already - it's dying soon. Don't WOT anymore.

To be exact i am not even sure is the gearbox even slipping, considering when i go WOT in 2nd gear onwards, the car just launch forward like mad. I am kind suspecting fuel cut or boost cut. The gearbox is kinda low mileage too, a little over 100k km's when i first got it.

It came out from Crown Athlete 2002, the last generation of 1JZ. Let me seek more opinions, my gut feelings telling me it should be something else.

dude.. this is a different thing man. Fuel cut and boost cut feels very different.
