Every time I snap the throttle the car goes lean and sputters most noticeable on a cold engine it seems to slightly get better when the car is at operating temp "sounds like a subi" but if I slowly get in the throttle its ok it will rev up like it should. Ive tried to richen the fuel map in the areas where it goes lean during tip in but that doesn't work. Ive also tried to play around with the Accel fuel settings but nothing seems to work..
I know there has been a few threads about throttle tip in on AEM but I cant seem to solve my issue Ive tried many different settings but I just cant seem to figure it out.. Does any one have a solution? Or guide me in the right direction.. I would greatly appreciate some help..
I have an EVO IX with a 2.4LR My mods are in my sig. If logs are needed ill get some just let me know what to log and ill post it..

 

Still having issues. Im starting to think there is something wrong with my EMS... I just installed a double pumper setup (2) punched wally 255's. The problem is still there but seems to be worse than before with the single 450lph. Ive got fuel pressure @ 43-45psi with no vac. Anyone care to chime in?
I would greatly appreciate any advice.

 

Don't add to the fuel map to compensate for a lean tip in. That should all be done with the accel tables.

Ensure that the fuel map is as accurate as possible, then work on the accel tables. Accel tables are very tricky and are near impossible with an incorrect fuel map. Here is a link to a reference that I use.

It sounds like you are tipping in lean and then, based on the sound the car is making, you are going rich. You can try to increase the Dtps sensitivity to have the accel fuel kick in sooner. And reduce the accel limit so the accel tables don't inject too much fuel.

A screen shot of your accel tab may be helpful.

 

Thank you eeweeks that link is very helpful. Here is a screenshot of my accel tables
I will give some updates this weekend.. Happy Thanks Giving
