Re: tune check

your maf is jumping around way too much to dial it in. You need to put some screens on her to tame the maf a bit.

you also have the maf clipped at 900 counts.

why not use the custom tune and proceed since your a premium member?

Re: check my math

the most correct and easiest way is going to be dial it all in on the stock tb and get it perfected then swap the tb and dial it in. That way your not fighting the tb fuel spark and everything else all at once. Or you can just load in a generic predicted ff throttle table (like the 62mm table everyo...

Re: check my math

you got it

no you still have load scaled same as before

SD scaling isnt necessary but you can just simply scale the map at 0 aircharge, fuel pump voltage x axis, and adaptive airmass functions.

Re: EEC5 limits/scaling tune

you need to reset the kam power when swapping strategies. So leave the battery disconnected over night.

if 25% causes a no start then lean it out 15%

Re: question concerning engine dyno test

On the ford coyotes the relearn is usually not completed due to the software asking for the relearn procedure not being coded correctly

Not sure if the GM your experiencing it on would be similar.

If using hptuners to try the relearn use something else.

Re: HEGO1 and HEGO2 reading low voltage

impossible to say without more info

did you do the cbaza swap and run a cbaza swap specific tune or did you swap over all the differences instead?

It sounds like its obviously not in closed loop. You need to get it in closed loop before you can tell anything.

Re: EEC5 limits/scaling tune

Here's a base fbgi0 tune. This should get you started. Downloads the fbgi0 def off the homepage for tunerpro load the xdf and adx in to tunerpro. Get it fired off and going and then start dialing in the maf. The more you tinker the more you'll learn. FYI i set the engine size to 471 cubes thats 1.75...

Re: EEC5 limits/scaling tune

There is no accurate data for the frpp LU47 / 47 lb / 52lb injectors used in the GT500s. The stock tune data and published data is all wrong. You will have to manually dial the injectors in. This no doubt is whats causing your fueling issues. Terminator and Stock GT has the exact same engine size it...

Re: need help in a few areas

fuel can be as far out as it wants and you may never have an issue so long as the o2s can correct for it some engines arent that tolerant though so its up to you as the tuner to decide if the maf counts do not drop below the idle maf counts on decel then changing those bottom areas below idle wont c...

Re: Car going lean at half throttle

If you have an MSD distributor you need to throw that away and upgrade to a stock distributor first. You should not be going WOT on an msd distributor regardless as its not safe. Intermittent lean spikes on a wot pull is usually a misfire. Most likely the msd if you have that. injector timing has no...
