That's what I'm researching.

 

If it won't work, I know it can be done using just the factory ecm, just have to be creative. I'll figure it out

 

I believe it can be done, I wish the newer modules had the cos to do so easily....I would like to use that controller even on a wet nozzle setu, would be nice not to have to cut timing!!!!!

 

Now the timing is no big deal. I can run all my timing or have nitrous timing right now with the IAT trick.

What I'm looking for is a way to control the fueling when I switch to dry

 

you can use the IAT trick to control fueling as well. Check out B3641 - PE Modifier Based on Intake Temp....

 

THats gonna be a toughy without a MAF....Im trying to think if there may be any modifier tables that work in conjuction with the VE to get you there. But the problem lies here, the IAT trick is going to be increasing the IAT values seen by the ECM, so in theory that would tend to Lean out the VE if there is a modifier table that references IAT vs rpm etc. to modify the VE....Im not at my notebook with my software but now you have me curious...will dig around a bit.

 

Thanks corey, I just found that about two seconds before you posted that. Can someone send me an efi live tune file. I'm at work and just downloaded the efi live software. I need a tune to look at to look at how these tables work together. danparker005@gmail.com

 

AHA! Great minds think alike...lol J/K. You'd have to alter those values "against the grain" so to speak since generally cooler iats will require a richer mix, but the interface is going to be showing the ecm hotter iats to drop the timing.....should be doeable tho with the pe modifier. Good catch Corey

 

check out this thread, it has been discussed before

here is a tune i had handy

 

Bad ***! For a guy that already has enough injector to handle it, this would be a clean setup, and run around full power na at the same time
