EFIDynoTuning Forum

I was able to get it to idle. And some part throttle. Had a couple other issues arrise. Maf is fluctuating up and down in 22-34 point swings.
I tried reclocking, to not much avail. Currently back at work,I only get time on weekends

T4M2 was the base tune.
i edited for Long tubes under the HEGO Delay, decipha said make them all 20 in a previous post of mine.
i added the maf transfer from here under universal 90mm slot maf.
patched for 80lb injectors
pulled -12 timing from all the top columns in the borderling timing table for boost
"recently" edited for crank PW which is a very very low number, but she now starts.

Yes ive used compare data before when i was looking at my base tune vs the t4m2 to see what was changed to make the tune more tuneable. i actually have been keeping notes of what i change.

Here's the tune file
i updated the FN348A by multiplying it 0.23. ill try and see if it made any difference in a few.
But if there are any other mistakes in the tune let me know please. i thought i had it well rounded, but obviouslyi did now.

I'll post it when I get back into town to the laptop

I didn't scale the table as you're stating. That could highly likely be my entire problem. I'm unsure whether clear flood mode is even working.

Fuel pump is priming to 40 psi for 3~ seconds and then turns off.
Plug wires are in the correct order.
Tach and datalog register 180-250rpm when starting.
Vacuum for the regulator is going directly to the intake manifold.

I'm thinking my cranking pw needs to be rescalled for the injectors as I do not think the tuner pro patch for 80lb injectors changes that parameter.
When I get back into town we'll try starting it
If that makes no change then we will loosen the distributor and see if it will hit off by rotating it lightly one way or the other. But it was set dead on 10btdc before putting the blower on. Timing wasn't altered.

Im really kicking myself in the nads right now....... setup as follows

Stock 302 (larger main and rod bearings)
E7 Heads
Vortech V1 (no belt on it as im trying to get it to start for the first time)
80lb Deka Injectors
aeromotive1000 set to 40psi
ford slot maf in a 90mm housing placed pre blower
explorer intake

Im killing batteries and jump boxes left and right. first try to start no fire at ALL not even a hit. started to smell fuel so i quit trying and went to work. came home, unplugged fuel pump fuse and tried to turn it over again. HORRAY it hit a couple of random times, but no start and die. so i tweaked a couple of things(cranking PW) and even checked to see if the maf data was corrupt(it doesnt appear that way) im asking if there is anywhere i can look to maybe get this thing to at least fire and idle so i can go back about dialing in the tune for idle and etcetera.. before i send it to the dyno ill post the .bin if it helps when i get home.

How far does the delay need to be adjusted for a set of longtubes?

I remember there being a topic on this forum before "the big clean out" on tune alterations to hego parameters for long tube headers so that it would compensate in the different exhaust pulse that long tube headers present.

I was curious if there were parameters that need to be changed, and if so what they were.

Okay, thank you for the quick search of member name.
*Note that if you click the 'blue text' that says "SailorBobhere" it takes you to forum message sender with MBSVT name highlighted. I've tested it a couple times with this result

@decipha
I'll spend some time toying around with it to try and learn it better. i see the possibilities in TPrt, but i think the only reason i like BE is because alot of the extra "nands" is taken care of for you where i need to learn how to successfully datalog and located directories within TPrt

Thank you, I'll see if i can search his name up in the members list. i see you've linked his name to an account "@MBSVT" in the forums. is this his new handle?
