Just tried converting my other car to a 3bar SD, and get very similar results. Car is way too rich to start up due to the PCM giving too much injector PW. ugh...

Wildside - If you turned off...

Have you tried using another PCM? I've got another one in another turbo 5.3 vehicle that I've got. Maybe I'll try it out on there and see if it makes any difference.

All of the ECT tables are at 0, and I took the VE table and changed all the cells in the area where the car starts up and idles to 50% of what their original values were. crank it over and get the...

As silly as it sounds, I have not tried this yet. I thought that what was good for the 2bar map, would be good for the 3bar map. Its always the little things that you forget to try. I'll give this...

I have been running my car on 2bar speed density for a long time now without any real problems at all. Decided its time to run more then 15psi of boost so I went and upgraded the OS to the 3bar OS. ...

Ya that sounds like what has happened.

Appears that I have fixed the problem!!!!! (whatever the problem was) Heres what I did...

Taking bills advice I converted it back to a stock OS. Made a few minor changes and took it out. Instead...

Wouldn't attempting to boost down the street with a stock OS in the car be a bad idea? I'm down to try it though. ;)

And just for kicks.... I took the BE down to practically nothing, and tried it again. Seems like its still pig rich, I don't really know enough about HPT to know what to go after. :(

and here is pretty much the same tune, with the BE at 1.0, and a log to go with it.

I got a chance to do a few more logs, with a few different changes to the tune.

Heres a tune where I adjusted the Boost enrichment to .5 and the power enrichment to 0.001(nothing) and a log to...

I'll log it again when I get some more free time. Thanks for all the help / suggestions so far though. I appreciate every bit of it.

So I took it out again for a spin tonight, change the cells on the BE to 1.0. and changed the PE to 1.27 across the board. Also changed the COT to 1.0. It pretty much does the exact same thing,...

Oh, right! I knew that. ;-) Thanks

Bill, thank you very much for the suggestions. I will try it this evening and get back. Just curious, what is the BE?

Just for S**t's. I took the boost enrichment table and went 1.0 across the board. Now while I'm at WOT, I am around mid 10's. Vs. Mid - Low 9's before. Its leaned it out a little, but still...

Anyone ever seen a faulty injector do something like this? Or how about if the MAF isn't failed properly? What kinds of issues might that cause?

Hello all! I have a strange problem with the car and would like to consult the HPT tuning guru's. let me know what you think!

Its a 2000 5.3 with a Twin turbo set up. Manual trans, 60lbs...

So I went on autotrader and tried about 4 different VIN's. Found one that worked and I was able to connect with the vehicle. Thanks for the help! Much appreciated.

Does it matter which VIN it can be? If I were to go on Auto trader.com There are plenty of 2001 Fire birds that have the Vin displayed. Would I be able to just punch in one of those?

Hello all! I have a 1971 Datsun 240Z with an 01 LS1 in it, from a 2001 Firebird. I sent out the PCM to a mail order tune guy who did some stuff for me to get the car running, like remove VATS, and...

Hello, My name is Dave. I have a 1971 Datsun 240Z with an LS1 swap from an 01 firebird. I JUST got my HP tuners today, so I felt it was a good idea to introduce myself. :-) I'm 25 years old,...
