got a new tune

[primhatch]

so i got a tune from a reputable shop in my area. I loaded it and the car starts then cuts off. will do this all night long. if i disconnect the coolant temp sensor , and intake air temp sensor it will fire run for 3 seconds then cut off. after about 20 mins of this it will fire and stay running but will not rev over 3000 rpm. . . . .
the computer is a 02 silverado 5.3 , no mass air , i did re run the intake air temp wires. no rear 02 sensors , has a gm three bar map , 5.3 with a 76mm turbo., 96lb injectors( updated from last time. ) e-85 set at 50 psi fuel pressure. mild cam. prop form intake 102mm intake. i dont have a data log as i dont want to keep doing this to the motor. so any thing i can look for before doing a data log tonight. . . thanks for the help

here is the tune

Ve table looks to rich for cam but without specs cant say for sure. Your stoich point is still set to gasoline. Your injectors are entered as 80's in flow rate only, rest of data is stock.

how to i change from regular to e85?

[mecanicman]

Use compare function, I have changed your stoich point. You will need to get correct injector data as well.

Your IFR and spark tables need work.

When you try to start it, have you tried to feather the pedal a bit until it starts or keep it running?

I'm thinking you are a tad bit rich as mecnicman suggested and need more air.

You might wanna try adding 2 grams to the entire base running airflow table and multiply the start up airflow initial table by 20%(1.20).

yes no response. . . after a while of unplugging the air temp , ect and map sensor it will fire and run , no throttle response.

Where are you located?

A see a couple of things that stand out.

1. MAF has been failed - it's set to 0hz.
2. PCM is locked (best tell tell sign of a poor tuner, imo)
3. Your fans are set to turn on before your thermostat opens
4. Your timing table looks, well, to be nice, special.


The VE table does look a bit rich, hell, it's more than my VE table and I've got a decent size cam in my truck.

It's a 2 bar speed density tune with no maf installed , it's supposed to be failed. And if tune was locked, you couldn't view it. It's o/s locked by hpt cause of custom 2 bar o/s, any hpt can use it, just not other tuning software.
