So I've been working on an engine swap project, ecotec into a foreign car, and what I thought was the right ECU ended not being it. I read the computer and it came up as a 2004 Malibu 2.2. The ECU is...

I'm more concerned about the drivability according to my log

Well I finished the cam and headers install. Performed my initial cam and spring break in. Everything is great so far. Once stress was put on the engine I am assuming that the oil had thinned out,...

I'll have to give that a shot. Thanks for the input.

Would it be wise to not adjust anything if it idles and drives ok though? If I can get away without touching anything it would save me a cool $100. I'm just concerned with potentially damaging...

Morning fellow tuners. This weekend I will be installing a cam (.050 229/242) and headers back (test pipe), along with my intake.

It's been about 6 years since I've touched HPT.. Not even sure...

Upon my research I haven't reached a clear answer. I am looking into getting an ECU for my build, problem is that it's from a donor car that is a different model but same ECU. Will I be able to do a...

I am running 93.. Just gapped the plugs down to 0.035 and did a case learn anyway. Runs great now and no more misfire. Will be going on a longer journey here in a few minutes and hopefully everything...

new plugs are in the car.. rechecked the gaps and where at .041 .043 .041 .044 .... I re-gapped them all at .035. Going to see how it runs now, sounds great sitting at idle right now. Will a case...

got the cam cylinder fixed, the notch wasn't aligned right and now it's good to go!.. I still have a misfire issue though. I'm thinking maybe the plugs? or even a case relearn? Whats the process of...

guess I should have done some research first, but I think the cam sensor might have been installed wrong. Gonna check it tomorrow

So I just rebuilt my engine and finally got everything installed. Fired up on its second crank. Right away got 2 CEL, P0017 Crank Position - Camshaft Position Correlation Bank 1 Sensor B and P0300...

appreciate it!

I am looking for a true stock tune file for a 2007 Cobalt SS/SC (LSJ) asap!

Thanks in advance

I have a torque dampener installed and about to install trans mount and the linkage bracket here in a few weeks hopefully. Everyday driving is great, have had no issues even taking it up to high rpms...

reason I am asking is that I am in a pickle between building a LNF or LE5 RWD application. The LE5 parts, especially block, is very easy to find compared to the LNF. If I can properly tune a fully...

Are there any updates on adjusting the cams for the LE5 ecu?

So I don't want to make a new thread about some LE5 tuning. Anyways, how is the tuning going? I'm thinking of throwing a turbo on a LE5. Are the ECU's for the 2.4 any good to tune? Just trying to see...

I'll prob just try out that bracket first. Who knows could be a cheap $20 fix

It grabs about mid way, probably a little more to the top. There isn't a whole lot of free play when fully released. I'll have to check ced for the bracket. Never knew the LNF's came stock with them,...

well i found a few upgraded parts on ZZP.. thinking of going with these first since they are cheaper than doing transmission work.

Adjustable Clutch Rob:...

well it doesnt grind going in nor does it pop back out. Just doesnt go in, could be driver error who knows. Its perfect under normal driving conditions

I'm having an issue shitlfting from 1st to 2nd when at the drag strip. The linkage isn't bent or anything and I have the act 6 puck sprung clutch. It's like when I shift it feels like it goes in but...

well i have the afr floating around 14.7, just goes lean for a moment then comes back down. You gonna be at the meet tonight?

I gotcha, I've zeroed out those tables and have plugged in the injector values. I also have my idle at 950. I'll see what happens here in a few. Would adjusting the ETC scalar help as well? Last...
