That is the table at Injection timing> Normal ECT ?

Thanks for the insight

Yes it seems to sit at about 56-57 depending on temp

Its an in tank Walbro 255 running to a Corvette regulator/ filter then to the rail.

Stock LS3 Injectors. I've attached my tune here for reference in case you want to double check my settings on those.

Is it considered normal that the car would act one way in 15 minutes of in town...

I've made many more adjustments and the car is getting close. I'm fine tuning the MAF before reactivating the VE to dial that in. My question is I have two logs from the same day that give me very...

For now this is it, I just thought adjusting the MAF more after I had already decreased 15% in the lower values was a little unsettling. If it isn't alarming to anyone that knows better than I, then...

I don't have the wideband hooked up, I'm just going by the fuel trims. Well that and the fact that it stalls every time I back it up and just generally acts like the fuel trims are accurate aka runs...

Attached is my tune and 2 logs from drives around the block tonight. I'm running MAF only and already adjusted the MAF values down 15% from stock. Why is it so pig rich? I feel like I'm missing...

Just wanted to update this for anyone in the future. Last night I changed over all the ETC tables from my Truck E38 to the settings from a 2010 Corvette (one that uses the Gold blade TB). I had...

Right now it just doesn't seem to act right in part throttle situations, "breaking up" is the best way I can describe it. It's not tripping any codes but I always thought for example that a gold...

Can anyone with experience chime in here, I've had both major swap companies now tell me this is doable.

The question is can a C6 corvette pedal be compatible with a 2008 Silverado programmed E38?...

Will this work? I've had a hell of a time dialing in the tune in my 68 Camaro. It's got real bad stumbling issues on light throttle and seems to be all over the place on fueling every time I run it....

I just realized there are alot of misfire detection tables I need to edit, I did that now and will try tomorrow to see if that helps. I think a bunch of my trouble is coming from the PO300 code. Once...

Can this be done?

I'm at my wits end trying to get my 68 Camaro rolling. It has a cammed LS3 in it and I cant get it running good enough to even make it down my street without stalling and going...

I took a shot in the dark that the tune was too rich and after some adjustments to the VE and MAF it runs! I made three trips yesterday just around the block and such.

Today though, on my way to...

Made it off the ramps and out of the garage!!!

It died in the driveway basically at the very hint of throttle, but it's better than yesteday.

I have attached the current tune and log. I think...

Does the harness actually connect to the 4 pin connector on the alternator? Most swaps simply take the correct wires off the 4 pin connector to a switched 12v. This then excites the alernator totally...

OK just so I understand the 2bar upgrade does not in any way mean I cannot use this ECM. It means my VE tuning will be done thru the IMRC Open/Close tables instead of the way a typical 1bar E38...

Do I need a different MAP sensor other than the stock LS3 one to run this ECM?

Looks like the 2 bar OS is what I am stuck with unless I get a different ECM? Damn this sucks.

Moral of the story, never buy used parts.

Should I just load the 08 Corvette tune into the ECM. I have been manually copy and pasting the tables but perhaps just writing the enitre ECM is the way to go? Then I could read entire and change me...

All I have is the 2008 Corvette tune from the repository. The ECM cam with some of the junk you noticed (like the VE table.

Can I change back to a 1bar OS that easy?

I basically wanted to put...

I reset the codes and used the Electronic throttle settings from a 08 Trailblazer SS. It idled for a bit longer and died the instant I put it in reverse.

I can't get much of a log as it won't stay running long enough.

Regarding VE I just want it to have the stock 08 Corvette values. I used that in all the coeffecient tables, so what have I done...

I'm getting P0068 and PO106 codes
