When He bought the...

Ok, so that is a no.

How should we go about correcting our knock sensor tables for the new sensor placement?

Bump as well, would like to know of direction to go with it. Should we copy the parameters for the knock sensors from a LS2 car and put them in our ECU?

If i recall the LS3 90mm (gold butterfly blade) wont work due to it opening the reverse direction than the ls2 and ls1 style throttle bodies.

they would have a hard time backing up their case if your friend wanted to put up a stink about it.

I checked and did not have any codes set. I reflashed (which cleared the safety mode) and spent 4 hours tuning my car sat night. I only got the safety mode once, and it was at the begining, and it...

I havent checked today if there are any codes set yet. I pulled into the parking lot at work and the car stalled and upon the attempted startup, safty mode set and I said F it. I left the car where...

In the ls1gto.com thread, there is another tune further down labeled as "all new" That is my current tune I am working with, I threw out the "webable" one. I am sorry I didnt specify that.

I appreciate the lack of help from anyone. Thanks.

The damn car keeps going into "safty mode" still, no matter what I do. Also, I can not get the fuel to anything I command it to. The Lambda err...

and this is what I get when I try to upload my tune as an attachment on here. Keep in mind that I have been able to attach 2 other files already, yet when I attempt to attach my tune file, this is...

thanks 69lt1bird. really thanks. You have helped SO much. How about you stop fussing about how I chose to mod my car. If you had nothing positive or constructive to say in MY thread, you should not...

WOW, ok so no help then?

The injector data wasnt scaled, but I am running Greg's injector data in the tune. I said that in the email incase you were to post the tune. I did not want to get into troble for posting a copy...

I was messing with the injector boundarys in order to get my idle fueling some what corrected, as with the large overlap camshaft, most of my idle fuel was being sucked out of the exhaust before the...

in order to run the 60lb injectors within the 63.5 Limit in the E40 ECU, I have to scale by at least 80%. That is why certain things are scaled back like that.

I followed this scaling method. I...

I attached a screen shot of...

Ok, I have been fighting my car tooth and nail lately. I have really bad bucking problems. And now I am having random "Safty Mode" coming on. I can reflash the same tune in the ECU without changes...

HP tuners doesnt have the option yet to tune your brake lines. :)



Seriously, you may want to look for a specific auto forum for your cobalt for information like that. I assume you will be...

ok, after that last attempt at messing with injector boundaries, I had undone all of it and put it back to stock values. I have been cleaning up the VE table still, I cant seem to ever get it to stay...

can you post up a pic of the timing maps for me to look at?

does it explain the injection boundaries and such in the book? I am trying to find something that will help me modify when the injectors open when at low rpm/idle (high overlap cam) And does it...

ok, im kinda realy peeved and tired of this car right now. I have have been making slight changes over the last few days. I will log the car, check the histo's and change some more.

So far, like...

I posted 4 of the idle spark tables in the spread sheet

ok so in the "injection Boundary" table I added 35 degrees to what was there (520) for a total of 555 in cells from 0-1024, and left 520 in the remaining cells. I also had to change the "minimum...
