You really need to start with giving an injector part#, brand and supplier and a link to injector data info unless these are GM injectors. Unless I...

i want to thank you both verymuch for taking the time to help me. i just dont want blow this thing up. i havent held the pedal to the flor ever since...

it is vacuum but i dont have a vacuum line going to it. if i do dont i need to change the 36lbs to more settings?

Digging this up after a search. Does anyone have an unmodified LT1 Connect and cruise file available as a reference? The link above appears to be...

Well no offense but I cant even imagine this running in ""decent" category...

Good observation Can you get into Tow/Haul, Sport shift mode (not sure if you have it), but that table would definetly shift different and keep you...

such hostility.. please be civil. there's no need to constantly be a dick.

How about the vacuum referenced regulator?

And since you actually have running problems, I would start on the vehicle end, not the MVPI3 end.

I would drop down to even fewer channels 4-5 and see what happens as a test. If it still acts up, you need to be tracking down either a MPVI3/cable...

so change the map to bar 1, what shoiud i set the min injector to , and then lower the shift scheduling , it was stalling i had changed the folloer...

Another software engineer that thinks they are a natural at tuning. You are in a gen3 forum and trying to defend something that one of the more...

This is has it as an option for sure

I'm using and MVPI3 and 5.1.2682 Beta

I am using a pair of Spartan V2's. They are in my channels and pulling data being transformed to EQ what i have found from playing around with it...

You can make them ramp up higher with ECT temp, which is what I do for the summer. I make them stay on 80% after 190 deg

Well, you may wanna use the 1 bar for now, 2/3 of the voltage resolution you have available is being reserved for manifold pressures you cant achieve...

your right. i do have it at 39. i hit the wrong button. dyslexic i quess. lol. i changed to 36. im tuning the ve again .

The guy who tuned it seemed confident and it did drive great. Am i setting up the histograms correctly?

You'll most likely always have that bucking in the same range regardless based on the cam specs.

I sent you an email this morning. I really appreciate the help.

The pink user math variable means you aren't logging that PID. You will need to add the analog inputs to your channel list and transform the voltage...

Greetings from Finland. Rookie to EFI tuning, decades history of drag racing and custom building traditional old US iron. Current toy is Procharged...

You may need to tune MAF and VVE separately. Here's a base file and some useful channels to get you on your way.

Looks like maybe you're editing the VVE table for "manifold switch closed" when you should be editing "manifold switch open". Or just copy/paste all...

Assuming you have the regulator connected to a vacuum source.. Here is the injector data for that. As well as IAT correction for card maf.

Do you have a vacuum referenced fuel pressure regulator? You injector flow rate vs kpa is flat at 39 Lb per hour, if your vacuum referenced thats...
