Tuning Help Big Turbo 5.3 FoxBody

[AdamE]

Having troubles starting my fox body. 5.3 single.turbo. mods in SIG. Wondering if anyone can give me advice on changes I need to make. Used to be tuned for nitrous with timing retarded and a lot.larger lift camshaft. Ditched the Maf and went speed density with 3 bar map.

You forgot to post the tune.

Attempt at attaching tune.

[RonSSnova]

First thing to do is to fail the MAF in the tune.
Eng Diag/Airflow/Maf Freq Fail High to 0hz
Then under DTC set P0101, 102, 103 to 0 Mil on first error
In your VE Table, copy the original from 15-105 KPA and paste into the same area of your 3bar VE. The numbers you have there will flood the heck out of it.
Your injector flow rate is certainly not for ID 2000;s? Those look like stock numbers.
Fuel/General/Flow Rate/Flow rate vs KPA
The rest of the injector data needs filled in as well. IDC website will have the data.
Stoich needs to be set to 9.77 for E85
You should also set the fueling to open loop. Fuel/Open and Closed loop/ECT vs IAT to 285 all of them
Your timing tables are all wrong, and I don't see any retarded stuff for nitrous there?

There is really a bunch of stuff wrong....are you sure this is the file you are trying to use to start this up?

[AdamE]

you're right, posted the wrong file. sorry


Here is the latest i have:
adam_turbo_fox_base_chad.hpt

made a bunch of changes and still having no luck...

[AdamE]

The problem I believe I may be having, I think it may be because the MAF will not throw a fail code. Stumped

[RonSSnova]

Can you maybe get a start attempt log?
Use the default imperial config.
See what the rpm is doing.
Might not have something connected?

BUMP: Entered the ID 2000 data and still not starting

boost referanced fpr?

[AdamE]

Yes MagnaFuel Boost Referenced Fuel Pressure Regulator

[Mudweizer]

Have you checked fuel pressure?

[mecanicman]

Load this file(its yours modified) and load this config. Turn key forward, start log, then try starting car and report back.

[AdamE]

Fuel pressure is good

THANK YOU TO EVERYONE THAT HELPED!!!!! Turns out i FU**ED UP when i painted my coil brackets...... ill be HONEST and admit that, yes indeed, i put my coil wires on reversed, on both banks of the engine...... But for whoever cares, there is the link to the startup video!

Now who wants to help me tune this beast and make some POWER?!

[RonSSnova]

Very cool! Really similar to my setup right down to the side exit exhaust.
I sort of figured it was something simple......
Mine lit first turn of the key. I was surprised

startup scan 1.hplstartup scan 2.hplstartup slight rev.hpl

Startup 1 - is the initial startup into idle

Startup 2 - is idle

Startup 3 - is idle with some slight rev

Anyone care to take a peak and give me any input?

[Pekka_Perkeles]

Remove MAF PID from your scanner, as you don't need it.

Otherwise the last log I checked looks normal; at least the PID's you were logging. Although narrowbands did not switch, but that's normal after startup and since you did not have Status Bit Display populated with closed loop parameter, I cannot be sure. Also there was a tiny bit of knock.

Please remember: never trust just one opinion on Internet forums.
