I have already updated to the latest 3.6 and re-polled....no change, tons of channels missing. I'll contact support, thanks.

I'm good with how to tune it (the file posted isn't my work). The problem is I have hardly any pids in the scanner. Hard to tune anything if you can't log what's going on. Copying stock data back...

Since I don't have the original file....to start over I assume I can just grab any '07 truck file, license it and write entire?

The truck is on e85 with 127lb injectors. Nothing is scaled. The truck takes 30 secs of cranking before it will barely fire, then afr is all over the place. Once it warms up some it's drivable, but...

Preface: This truck came to me after a couple "shops" tuned it, and it's a complete mess. Attached is the file as I pulled it from the truck. It's got custom OS 1250212 in it. The main issue I'm...

I forgot to update this thread......everything in the tune was correct. The problem ended up being a faulty brake switch. Once that was replaced everything functioned correctly.

I'm at my wits end here so any help is appreciated. This is a 2000 fbody with heads/cam/3000 converter. Everything works as commanded except for the converter lockup. It will not lock until TPS is...

quick drive around the block....ethanol % never changes and doesn't seem like fueling is set up all the way correct yet. There is no wideband hooked to my interface for this log btw, but there is...

I set offset vs press vs IGNV table to the data provided by deatcshworks.....is that what you're talking about?

Does the Flex stuff all look kosher?

I believe I have most things fixed, stoich/ifr scaled correctly now....with CL enabled the car now starts and idles fine. I have enabled Flex Fuel but I'm not sure it's working....I only have one...

There is no maf on the car. I did some reading on the double stoich & half ifr scaling and will give that a try, thanks! I know the injector data is wrong....looks like map sensor too after some...

A friend brought me his 2010 turbo vette to tune after having bad experiences with a couple shops. I have attached the file from the car as it was delivered to me, and I do not have the stock file. ...

I did try populating/tuning the MAF table, but it never made any difference. Still wouldn't even attempt to fire.

For the most part it's what I'm running, with VE table and timing changes which really shouldn't have much bearing on cranking.

I figured out what's happening but not how to fix it. It turns out that even with a 2 bar SD operating system, any time a calibration is flashed into the PCM or the battery gets disconnected, the...

Had some time to tinker with this some more and am stumped now. Turns out hot starts are NOT a problem. It fires right up heat soaked with just a bump of the key. However if I flash a calibration...

This is my personal car that I'm just getting going. Details:
98 pcm
370ci
twin 6165
10.3 SCR
2 bar SD
e85
FIC 160lb injectors

Still early tuning stages. I've got it running great up to...

Thanks guys. Left it at .77 and 15*, plugs look good and the sucker rips on the street! Anxious to get it on the dyno/track.

What are you guys normally targeting for lambda under boost with e85? Somewhere in the .76-.82 range? Where are you seeing best power? This is my first e85 car and just street tuning it until we...

I think he wants to stay under 10psi and it's a stock motor otherwise, hence my thinking of stock OS and MAF. Pump gas, no meth, intercooled. If he has a desire for more boost than that I'll...

I've been using HPT since it's infancy and I do about 15-20 h/c/i and nitrous cars a year in both SD and MAF, but I'm going to be doing my first turbo car (sts C5) in a couple weeks. I'm a nitrous...

OMG this would be fantabulous, I have tons of people that would love this.:pray:

Didn't mean to step on any toes or fire anyone up, sorry! Perhaps I wasn't clear----You absolutely need enrichment fuel with nitrous, but your final AFR does not need to be much richer (if any at...

Not true. Too much fuel and/or too much timing is usually what kills motors on the jug. Rich is not safe.....rich lifts ring lands.

O/P: Ignore what the wideband says and tune the spray with...

TR6's are a step colder, but they're still a projected tip plug---not a very good idea with nitrous. Just because lots of people run them on smaller shots doesn't make it right.:) Nothing wrong...
