lt1 tuning help?

[Fuzzy from MN1988]

EGR Electrical Failure, Error 27 EGR Diagnostic, Error 32 <-- I will check over the vacuum lines and the EGR valve/solenoid tomorrow, should I replace them since I'm almost positive they're original.

VATS Enabled. On a stock 94 SS it's 'set' where my tune it is not. What would be the benefit of disabling the anti-theft?

Air Pump Diagnostic, Error 29 I'm guessing the air pump isn't set in the pcm anymore or something is wrong with the pump?.. None of the A.I.R. pump has been changed by me.

I went to my car to program it again and still nothing.. start and die right away. Once I put the bin file that was originally in the car it runs fine.

Yes replace them if they are that old but still might not fix the issue. Can look at that later... is there a EGR tube from your headers to intake? Was it turned off in last tune?

Turning off VATS is common with aftermarket tunes. If you loose your pellet key or the cylinder in steering column goes bad the engine will still run, if it's a conversion engine to another vehicle without VATS module and steering column it will still run. If it is an SS and this went bad it should not crank over either though? But you could turn key on and jump the starter solenoid and start car. In the 9C1 Police option there were no starter disable from Vats, just fuel disable from VATS. Aren't you the one with early $EEB? If so you have such an early SS with an $EEB I wonder if something was changed and it was closer to a 9C1? Do you have the stock factory bin file or just the mail order tune?

Uncheck the VATS and give it a shot! Your car is doing exactly what a VATS issue would cause.

Air Pump Diagnostic, Error 29 I'm guessing the air pump isn't set in the pcm anymore or something is wrong with the pump?.. None of the A.I.R. pump has been changed by me.

But have you owned the car since new? Disabling Air Pump is common practice as in 95 it was found to have an issue of collecting moisture and letting it into exhaust, since it was not needed to pass emissions there was a factory TSB to plug line at air filter inlet, remove relay and reflash PCM to disable. Nothing is removed.

You should do this anyway, there are 2 checkmarks to disable, one turns it off and one turns off the Check Engine Light.

I have the stock bin file available(found on this site), I tried that file with no success. How can I tell if it's an early $EEB or newer($EE)? I should be able to just flash a new tune with no problems right?

The only flags that were set on my mail-order tune are the ones that I listed. Error 27, 29, 32 and the V.A.T.S. I planned on replacing the EGR valve/solenoid anyways, I did replace my vacuum lines so I will check over them again. I wouldn't think that would make the car die right away though. I will try disabling the VATS and A.I.R. pump. Where is the checkmark to turn off the CEL when you turn off the air pump?

I don't think the EGR was turned off, only issues I see are the 2 flags. How do you actually turn it off? Don't you need to block off the ports if you disable it? The 3 EGR enable scalars are all set to stock.

You sent me your bin file once before didn't you? It was early $EEB. I have flashed 2 $EEB with newer $EE now with no issues...

Turn the VATS off and see if it will run.

Or post bin that runs and one that does not and I'll take a look at them.

I got the tune that I made to work, had to switch the VATS off. I tried the SS file without turning VATS off and it wouldn't work. The anti-theft was the answer. I'm going to try and switch it off with the stock one and see how that works. I couldn't get TP to work right when I took it for a drive to see how it handled and to log the info. My ALDL cable kept wanting me to switch between the Comm port 3 & 4, I had to mess with that more than once just to get WinFlash to work. In TP when I tried to connect I would get Data Connected(blue) and Data Error(red) flashing on the bottom of the screen. I never got an error message why it was happening with WinFlash or TP. I tried Start/Stop Data Scan and hitting the button that has the blue arrows pointing opposite directions, neither worked. The cable is brand new so I can't see that being the problem.

I did like some of the Normal Mode shift points switched to the Performance Mode shift points but I definitely want to learn how to change them around to make it better suited for me. Is there any additional equipment needed to watch the tranny? I know in TP it has it's own separate Monitor and Dashboard but they never change. One thing that I didn't like about the custom tune is that the car got a lot warmer than my mail order tune. I noticed on a tach that I have in my car that once it was warmed up it idled in Drive at a stop light at about 4-500 RPMs where my mail order tune would idle at about 5-600 RPMs.
