Hey, I tried logging into my account on the main page and it seems my password doesn't work. My problem is when I use lost password, it has my old email, which is not activated anymore. Wondering...

Lol yea, ok so We had the cav running really good till a rod siezed and blew a hole in the block, so we put in the second engine, with a new cam also, and all things seemed to be good, except we...

Like he said Smooth it out. Your car will have a more solid feel, and be alot easier to tune if it's all smooth. if your fueling is better and you still see KR, try lower timing a 4 degrees and...

Just a side not, why bother changing the afr leaner past your tq curve anyway, to stay safe after your tq peaks drop richer in afr to keep the cylinders cooler, which I run 11.8, which you a hair...

Yea we just got the new wideband sensor in today, watiting till tomorrow to plug it in. Unfortunetly my car tonight blew a ring so now hers is more reliable than mine for a change lol.

I understand how to adjust for 60's but before anyone understood to change the Volts multiplier table you adjusted the MAF table which is not a wrong way to do it, since the only TRUE way to adjust...

With the help of a few people (Phatcav0260 and DaFlyingSkwirl) The Turbo Cav is finnaly up and running. Right now it's running almost tuned, since while we were tuning with the wideband, half way...

First off, look through the forum, I've been here for a while, and unlike your 07 the 05 and 06 some commanded 13 afr. WHICH is still "ok", STOCK.


I don't think you understand the MAF table, ...

For now I'd leave fueling at stage 2 file settings with HPT, unless taking timing away isn't helping. Adding fuel isn't always the right, knock retard comes from BOTH to rich and to lean.

And I...

AFR and knock lol

Look at the Injector pulse width, they still open, I understand your saying it's acting as a air pump, but I've never seen either of my cars in dfco cut fuel 100%, I wouldn't want that since cutting...

Post in the general forum there are alot of reputable tuners there, that don't visit the 4 banger section much.

Saying leaner then 11.8 is risking your engine is false. First off some ss/sc's run 13 from the get go, I run 12.1 with a ton of power. Really you should start with 11.8 and work your way up to...

Well.... it doesn't cut them completely lol or else your engine would stall, your still pumping a little fuel, hence why I said lean, but close enough lol.

Sunburst, you answered all your own...

Reduce timing in that area, Knock Retard is funny like that.

In that case easier just to hook up a new wire hareness lol

Assuming every wire on your harenass stayed in the same pin order should just plug in.. Although you'll def need to add the crank sensor, or you might have problems starting. Not sure if the PCM not...

Basically do what everyone does when boosting a car, Add alot more fuel and take off a bunch of timing, then get the car turned on and workout the fueling with a wideband, then add timing back.

Is it the instant you hit the pedal only, and also in low rpms, that's usually the cause of burst knock, you can disbale burst knock that early and see if it eliminates it. if not knock can only be...

You really didn't need to set error reporting with no CAT, unless your actually getting the error code. Usually you'll only have to disable secondary o2 codes if your not running a second o2. And...

Try reinstalling HPT, I didn't have this problem but it can't hurt. Also you can unplug the 3 connections on the PCM. Unplugging the battery should have done it if that was the problem, but why...

Decel fuel cut off, it runs the engine leaner when you let off the gas, helps save gas and cuts the ricer exhaust pop (which is unburned fuel in the exhaust) unless you have a backflow muffler then...

Closed loop enable would be best unless you don't have any winter, but if you choose not to enable it couldcause rough start ups. COT and DFCO being enabled are your choice, although COT will effect...

it's not that it's not VIN specific, it's cause the Stage 3 is a standalone PCM. It is NOT the stock PCM used in cobalts, hence why no support. Pick youself up one from a junk yard (since I assume...

Let me get on my laptop later on and I'll give you the scan config I use, but basically go into the histo config then table and pick the table that corresponds to the VE table in the editor. I'm not...
