Can't help you there but someone has got to know the injector flow and latency for those injectors. If you can get those 2 right, I can help you with the rest

I got a map made for this setup as long as you have a Fuel Pump upgrade as well. PM me your e-mail address and I'll send it to you tonight when I get home.

I'd revert to a 100***37; stock map, then only touch the injector scaling and latency settings. It sounds like you've been jacking with more than you should on the tune.

I wouldn't run someone else's map. Find someone local to tune it right. You never know what physical problem someone else might have tuned around with their map. They might have a leak tuned out in their map that could blow your engine.

Well this would've been very helpful to mention in post #1...

Is this a map you paid for? If not maybe you can post it. If you did pay for it, why don't you ask for support from the provider, since we're never going to be able to really help you blind. We'll never know what other things could be jacked up in this tune without being able to look at it. Especially since you started to mess with it, no offense.

Are you on a stock intake? If not, can you swap back to stock intake?

I agree you really need a fuel pump as well. And a wideband, while we're at it.

If these are modded stockers he shouldn't have to change the latency. He should have to change the scaler and probably tune the intake calibration table.

Well I just realized you also posted on Enguinity. There you mentioned throwing several CEL codes, which you failed to mention here.

Someone posted a map on Enguinity for you. Hopefully that will get you close enough, but really, you should pony up for the tune. The tune isn't the part you should decide to cheap out on.

I agree with everything Freon has said. Even if I sent him a map it would only be sort of close. Each set of modded injectors flows differently.

that's what i posted on the enginuity forum. Running injectors that flow roughly twice the amount of fuel with the same(read stock) fuel pump is nuts.

Yes the moddeds do tend to flow differently but for the most part you can get the maps close, the problem is that he's already started with a modified VF-39 map and is trying to make that work...who knows what was changed in that map he's running.

that was the old way. if you check out some of the threads in here, people are getting better results with leaving the intake tables alone, and changing the latency + injector scaling. and even tho they are stock injectors, because they flow a greater amount, the latency does need to be changes, especially in idle/low throttle situations.

read this thread for more details:
