Yes, don't want to melt a hole in a piston etc. It throws MAF/ MAP codes at idle now, not always, but after a drive, typical big cam idle I assume. It does lope on idle now and is usually ok. I...

Ok, there is about 40 degrees of exhaust valve closing difference from the stock cam to the one in it now, so I added 40 degrees to the 520 the tune had originally. OK, forgive me here, but without a...
Sorry, back. I didn't get the code off it last time it went to low power mode, sorry. Will get that this time. Was wanting to know what to put in for injector timing, it is set LS2 stock right now at...
I don't have the pro version ( I think?) but was using an old Beta one, so just uploaded all the new suite and it seems to work fine. I STILL had a high MAP reading so deleted the MAP PID and...
Sounds like great advice, will do that and reflash and see how it goes, thank you.
I haven't updated it since 2012, but the plane programming was then too, HPT did an update then. Another thing here, I have been messing with the GTO (my brother's car) for six months and it never...
OK, as I suspected, there is something really wrong going on with either my version of HPT, or something. Here's a screenshot from the laptop I upload and scan with, and this is the scan file with...
I don't have the specs for the cam at .050 here but think I can get them. Not sure what LSA is, but lobe centers are 117 degrees and overlap is 62.5 degrees.
At frame 109 MAP is off the chart at 329 Kpa, just before the engine goes into low power mode. I only have the chart displaying up to 105.
Am using the MAP PID that HPT came with, nothing different, not sure if that is it. I am confused, I guess, how a sensor can return values that have to be wrong, that is like 45 psi, and the program...
Hi, have an LS2 in a 2006 GTO, mostly stock except for a cam. Cam has a lot of timing, 278 intake, 315 exhaust duration, .540" lift. Just starting out tuning, I added 15% to the VE and it got it...
Likely the ECU is in low power mode if there are codes set. My E40 on LS1 will start in low power mode. if I shut it off and restart right away I get out of low power mode somehow. I have a known MAP...
Could you at least say what the engine is and the ECU is, and what has been done to the engine?
OK thanks, will look for that module then, any idea where it might be? Cruise clicks on the off again.
Ok I don't know what is going on with the cruise on this car. I see that there are cruise pins in the ECU, the thing engages and then disengages right away. I can't find any other control boxes etc...
Thanks, I will play with the power enrich some and see if that wakes it up more. He scared himself some after finding the traction control button and shutting it off.
Had hoped somebody had played with a stock GTO but I guess not.
Like the title says, brother just bought a stock LS2 GTO. M6 trans. What does this setup lack for tuning to start with? He will modify the crap out of it I'm sure, but wanted to start somewhere with...
Isn't that just badges and trim differences?
Thanks Chris. I am running turbonormalising, but other items are low stress, max of 4200 rpm, etc, so am looking for reliability and the least ECU 'bugs' if there are any. Is the E67 newer I assume?
For an LS7 or LS3 engine, which is the preferred ECU, and for what reasons? This would be for aircraft, no transmission, using the ETC, no CATS or security crap. Thanks to all.
Well I would help but I have nothing but the tunes for my wierd 'vehicle'. Don't think that guys should have to pay their dues so much, makes for a much harder road to start with. Some people are in...
Doesen't look right to me, they are typically smooth curves, and the highest low number must be the same as the lowest high number on the two maps. Take a look at a stock MAF curve in one of the...
Throttle plate is free, not gummed up or dirty? Take the MAF off and feel it by hand to see that it snaps shut on it's own.
Hmm. I don't know what the load should be on this, it has a constant load from the propeller, at 1700 rpm I see 40% or so, but who knows, that would be higher than a car would have it at steady...
