Ok.... so I am an HP Tuners guy because I've had it for years tuning LS based stuff etc. Naturally I stuck with it for my truck because for $100 I was up and running. Tuning wise it works fine, outside of not having a dsp switch, it's basically the same as EFI. Logging wise.... terrible.
Last night was the FIRST time I have ever been able to log my truck. I have posted on the forum before about getting it working.. nothing. Posted again and some guy had created his own custom scanner config file that allowd me to log all of 3 things. He was kind enough to send it to me. RPM, MAF and mph Nothing else works... and that's where he gave up.
Thankfully rpm and maf was what I was looking for because I am trying to do some real fine tuning of vane positions and squeak as much flow out of my turbo as I can without unnecessary drive pressure.
What I found was interesting...with my current vane posi and tune I am actually seeing peak MAF numbers at 3500rpms... and it's only dropping slightly up to 3800. I had my truck shifting at 3350, but I'm going to bump it up which should be slightly easier on the trans, and in theory I should get a touch more hp with the higher flow assuming my timing is dialed in correct etc.
I have tried a lot of things with vane positioning to get more boost out of my truck and it just won't do it in the higher rpms. I closed them down pretty tight and it made slightly more boost but felt slower, my guess is that drive pressure was through the roof and the motor was choked up so bad power actually went down. Boost being just a measure of resistance tells me I actually created more by inhibiting flow through the exhaust... if my worthless ass scanner would have been working at that time I'm confident my MAF would have agree that overall flow had gone down. Tried them opened way up, boost drops a little and smoke gets pretty bad 7000ft altitude can really suck at times.
Anyway, It's obvious EFI has the market and HP knows this. People post about new feature such as support for the LML.. HP's answer is: "not for a long time if ever, it's going to be kinda hard and actually require work to crack the computer" .... how about a dsp switch type setup? "uhhh... thats not possible right now and won't ever be most likely" .. why? because they don't have enough diesel customers to make it worth their time. Those of us who did buy their product are just SOL.
My truck runs good considering I tuned it blind folded .. just think about what other fine tuning could be done if I was able to log anything else
|Done complaining|
