Personally, i set it at 10.07, and adjusted the CPS until we read 10 on the timing light.

I did it that way as well. I was having trouble doing it other ways.

P.S. when your done with that comb send it my way:icon_bigg

I can send you a map when we get some tuning on it.

62-1
FFIM
750cc
TRD cams
Slight head porting

How did I miss out on this thread so long! Thanks for all the replies, and John for figuring the AEM out for me, there's no way I could've set this up.

Regarding the injector wizard and battery offset, it is quite simple to make your own battery offset compensation table if your injectors aren't listed in the AEM wizard. Just vary battery voltage with the car running and watch and correct the A:F as nessicary. Of course, you need to have an otherwise stable A:F first.

My experience with impedance mismatch on AEM is similar to Mr. Reed's. No smoke but it runs like ass.

The AEM will switch from the cranking tables to the main tables depending on where you have the crank exit RPM set.

I think thier software and interface is vastly superior to nearly anything else available and I've tried most.

Referring back to the boost solenoid, you can use a GM boost solenoid, GM Part # 1997152, and pigtails for the solenoid is GM Part # 12102747. It looks 10 times better then the big blue MAC valve that AEM uses, lower cost (less then $35 for both from rockauto) and works just as good.:)

Ha, wait till this weekend. Hopefully, all of these little leaks will be taken care of. You should post pics of the boost leak tester we built, too ;)

*edit*

Also, I was thinking Jeff - We should run the ISC solenoid tube back up in front of the throttle body. I know it will be a pain in the ass, but you're going to have a boost leak there if we just stick a filter on it!

i actually do have that also, i was just debating on whether to use it not. wanted to have quicker control over boost, but the gm solenoid might be a better idea since i can have 2 settings.

Does anyone have a simple diagram of how to connect the the vac. lines on the gm solenoid, including which port goes where?

ISC has a valve on it, seals off when the manifold enters boost.

make sure to check the timing at higher rpm though as well. My timing would sway 3-4* on my celica. Adjusted it per the manual and stayed solid throughout the rpm range.

Good call, I didn't mention that.

Jeff has a FFIM - and it doesn't have any placement for the stock ISC one-way valve, nor the little filter under there. Therefore, closed loop is the best way to go ;)
