Hey,

i recently purchased aem for my 98 vvti supra. It seems that i have 5 wire harness and previous n/a supra have 3. Has anyone here went with aem? i heard you can custom wire harness but has anyone in here done that before?

thanks

i'm confused. are you asking about the aem on your supra or are you asking about putting it on an IS300?

I have not looked at a Supra 98+ ECU. The only way to make a custom harness from the AEM and piggyback onto the existing harness. Whatever box you are using needs to be modified to do this unless you have the racebox. The wiring is the easy part. Next you need to get a cal that will run the thing - that is the hard part! Good luck!

lol, no offense but if your that out of it you are almost inevitably focked.

Even if you manage to get it wired into the car correctly(easy part, even easier if you have plug/play which I'm sure you do) tuning it will still be very difficult.

You best bet will be to take the car to someone who knows what they are doing. That or start reading on how to do it yourself. I have found that internet forums won't walk you through things and you have to do a lot of investigating yourself.

Eitherway good luck!

tuning it is not the problem

if he's trying to install aem on the IS, which he hasn't said, but i'm assuming, his real problem will be getting everything hooked up, synched, and working. it's definately doable. people do different car setups all the time, just have to have some electrical knowledge. I heard a guy hooked up an aem in a trd s/c tacoma in a day, but that person knows it inside out.

aaaaaaaaaa HA........

if you're installing a AEM on a Supra, why are you posting here? the obvious of SF and AEMForums not working?

Actually the AEM forums do not work as of right now and yes www.supraforums.com do.

You will find much more info there, check the MKIV, Dyno Tuning and maybe some of the sponsor sections for help.

PS: The Cal the 79se was referring to is your "calibration" that your AEM would use to run the car.

that's not the case. i've read it on aem's site before when searching about vvti control on the AEM. might not be terribly common though. still far better resources there than here for supra info.

Tuning is going to be a huge problem for him and he stated before it was for a supra not an IS, that's why I assumed he would have a plug and play unit.

Yes most all standalones are in essense universal. In case you didn't notice he didn't seem to have much "electrical knowledge", hence my reasoning for him being screwed.

nobody has been able to help the poor guy on Supraforums either..

hopefully Nigel can assist him...or maybe even Lance? how did he get the AEM connected on Kevin's IS?

not at all...

1998 non turbo supra came with the same vvt-i 2JZ-GE engine as the IS300...and it quite rare, if at all, to find one NA-T :p

tuning may be a problem for him, but it's not a problem. getting it hooked up and running is the tough part if there is no base map for startup.
