I had my stock ECU go bad and upgraded to an AEM EMS v1. I finally got it tuned enough to start, at idle it's rich and once I put any throttle it goes dead lean. In the tuning it seems like it won't give it enough vacuum but there's no leaks and it ran fine before the stock ECU went out. It has stock injectors, Cosworth 272 cams, AMS inter cooler walboro 255 and hks exhaust. Any help would be great, the AEM EMS came completely blank and a stock map or base map would be helpful and somewhere to safely tune my car. Any help is greatly appreciated

 

Stock injectors!? Figuring the fuel table was dialed in you shouldnt be having any fuel issues whatsoever. So it really comes down to if you know what your doing with the aem ems, I would just find someone local and have them tune it from scratch and save you some headaches.

 

Get rid of the stock injectors.... it sounds like you're new to aem. I would not continue until that's done.

Also do u have an ait sensor and map sensor hooked up?

 

The nearest shop is Oregon, I had a shop down here try and tune it on the stock ECU and they said it was wanting a lot more air then he's ever seen before and they tuned it really lean, it ran better on a stock ECU Map then the tune. But my buddy here is experienced with AEM and has tuned turbo'd honda's and EVO's but hasn't seen where it's not getting enough vacuum.

I do have 950 or 880 injectors that I can install, I do have a MAF sensor but not a MAP

 

You fuel map needs to be tuned. Or you have a dead MAP sensor, or your sensors are not configured correctly.

Send me a pm and I will give you my email and I can take a look at your cal. 99% of the time on an aem it is tune related or bad setup. If you are speed density, a vac leak will not matter.

Also post up the full specs of your car, engine, cams, injectors, turbo, fuel type, ect. Anything related to your engine.

 

Thanks I will message you

Engine:
2.0l 4G63
Stock injectors currently have 880's to put in
Stock turbo
Cosworth 272cams
Port and polished heads
Supreme fuel
AMS Inter cooler and piping
HKS exhaust

 

I changed out the injectors and put in 880's I can get it to idle warm but it still goes dead lean anytime I try and give it gas. I have made sure there is not vacuum leak the timing is good. I'm not sure where to go from here because it seems on the ecu no matter how much I turn up the gas it still goes dead lean when I give it gas and run rich at idle.

 

Send me ur Cal file. I have one laying around here on my comp for a setup very close to yours
