2008 GT500 Convertible
I’ll take MAF for 50, please.
It failed after I installed my ID 1050X injectors which was a "New Tune" with the HP software. I did, however, drive on this tune for about 1 month before this part failed. Everything was OK until I did my KAM reset. I'm thinking it was just a part failure and nothing to do with the tune, but then again I really don't know.That would have been my next guess. Did it fail after the tune revision?
By the way you were right when you mentioned a "sensor gone whacky". The print on the package that it comes in states ONE SENSOR and I hope that when I get this new one that it does not go whacky like the otha one did.I can’t see your tune or your PCM becoming corrupt. Something that can change has changed... hole in a tube, sensor gone whacky, etc...
Is this only since the injector swap. I've experienced a similar issue with mine when the engine is hot, but I've done a number of things that have remedied the issue. I also have cams that further complicate the issue. There are functions specific to cranking routines. You might have your tuner lean fuel out during crank and for warmer temperatures. Mine starts fine now.One thing I just remembered is that a few weeks before this part failed I would shut my cah off after it was warm I would try to restart it and it would crank and crank and crank maybe 20-30 times or more before starting. I would have to stop and try again sometimes because it would not start on the first try. I thought that this was odd and had something to do with the last tune, but now I'm thinking maybe not. Sometimes it got to the point that I thought it was not going to start at all. I will keep a close eye on it now.
I have the dual aeroforce gauges and 16 function is too much information. I'm going to reduce it to a smaller number like 8. Figure out what you want to monitor and focus on how to have that data. Most WOT functions you won't be able to monitor anyway, so they're somewhat useless. There are tattle tale gauges that can replay WOT routines. The problem with stand alone gauges is you only have so much real estate for placement. For example, my boost gauge can tell me what the highest boost it's recorded, just not what rpm it occurred. But really for WOT data, you really should log the car. I'd want to make sure the flash tool does that. I've always used SCT stuff because I'm locked into it by virtue of my software license with them, so I really can't comment on anything else out there. I'm sure HP Tuners has a good product too, but they're several years late to the game. These seem to have great user support through their forum. The more complex the PCMs are becoming the more tuning becomes a specialized discipline.Question:
Do you guys think I should stay with the HP tune and buy one of their gauges and a wideband O2 sensor to monitor some of my engines vitals or switch over to the SCT tune ?
I have the SCT 4, but I have nevah used it to monitor anything. I think I still need a wideband sensor for that too since my cah is an '09.
