just letting you all know i got my AEM EMS installed into my SC300 with the 1jz. i supplied my tuner with the power FC maps and he said that they would be different and wouldnt work and he built the map from scratch. he did a great job also! took about 5-6 hours on the dyno to get it done and its setup as a very very conservative setup atm. unfortunately i don't believe he wants to share the map at this time
that's perfect, I need your maps
However I do not understand why you cannot retreive that maps from AEMPro directly? It should show your installed maps, shouldn't it?
by the way, could you please provide me with your specs?
Not trying to be rude, but why would someone just give you their basemap when they likely spent a good deal of money with a tuner and dyno time to fine tune their car? I've read your posts and it seems that you want someone to do all the work for you.
I can shed light for you on your dilemma as clearly you need some help on this. The only real difference between a 1JZGTE and a 2JZGTE, tuning-wise is that the USDM 2JZGTE is MAF based where the 1JZGTE is MAP based. Additionally, the injectors on the 1JZGTE are wired for batch fire whereas the 2JZGTE is wired for sequential fire.
Now that said... The way to make this work is that you will need to purchase three items: 30-1100 AEM EMS (for the supra tt), HKS DLI, and a jumper, or patch harness. The patch harness is the easy part, I'd recommend you contact:
www.autosportwiring.com . If you want to speak to the owner directly, his name is Richard and his email is
richard@autosportwiring.com Richard is an engineer with American Airlines and he's been building adapter harnesses for years. HE is very knowledgable. What you will need to tell him is that you need a patch harness that plugs into your 1JZGTE vehicle's engine harness (i don't know exactly what vehicle you have) and that it is plugging into the 30-1100 Supra AEM EMS. He will build you the patch harness you need.
The question you will need to ask yourself is this... If you plan to stay on batch fire for the 1JZ's harness, that's fine... You need to let Richard know that. If you plan to convert your system to sequential fire injection, that's fine too. What you would need to do is merely wire the injectors directly to your patch harness via your own new wiring. Personally speaking, I chose to do this on my own application as sequential fire offers benefits over batch fire that I will let you research on your own.
The HKS DLI is an absolute must on a 1JZ/2JZ application if you plan to run more than 1bar of boost. The reason is that the AEM EMS runs the car on wasted fire spark. This means that your dwell time will be cut in half and your spark is much weaker than your factory setup. The DLI will help this situation, albeit, only a band-aid. You could be cheap and just run an extremely tight gap on your plugs instead of running a DLI, but your idle quality will be horrible and your fuel economy will suffer.
Lastly, the basemap itself... You can take an AEM factory calibration for the 30-1100 and make it work on your car easily. The sensors, believe it or not, are all the same. You would switch on the MAP for load instead of MAF. You would switch over the speed sensor input to that of a 87-92 Supra to get your correct speed sensor input or correct speed sensor for your car. The rest of the sensors are the same. The AEM only needs cam/crank signal, TPS signal and a MAP of MAF signal to actually run your car. Set the AEM to read MAP for load and the rest is the same.
If you're not competent to do this, I will send you one if you pm me. It's really simple. Please understand though, the calibrations that AEM provides are merely a basemap to get the car running; I would not expect the car to be finely tuned or fairly driveable. You will still need to have it tuned by a competent tuner.
Best of luck, I hope this helps.
