Why doesn't HPT change GM s/c LD9 timing????

[killerjuice]

ok, lets look over these timing tables, I have zero (0) in all the tables where I am running into boost, and all the multiplers at 1.0.

I understand my wide band reads 13-14, but the gauge and the AEM preset are about 1.2 off, and the sensor is about 6 month old bosch so those readings are incorrect. The actual AFR is about 11.5-11.7. Having said that you would think anytime I would be in the

HO (pe), LO (pr), HO (pe) alch, or LO (pe) alch, I should be running ZERO timing..... well lets look at this..




we were trying to pull timing and noticed that none of the numbers added up, so either you can't actually change the timing or I missed a window somewhere, could some one please enlighten me, thanks,

it would be so much easier for us to understand whats going on if you were to post your hpt & hpl files.

[IanB]

Get those files posted Garrett, this isn't over yet, lol.

[IanB]

Garrett sent me his tune and log files last night before flying out for work, I'll try and get them posted tonight.

[IanB]

Well here they are, what do you guys think?

[killerjuice]

thanks for posting those up man, hopefully we get some responses soon and find out exactly what is going on. I have 2 friends using MS and I can barely keep them under control because I went thise route, I am still happy I think it is just a small glitch somewhere...

seems there is a high TPS minimum spark table that i need to add.

Please email support with your .hpt file and also your serial number and a link to this thread.

[Chris@HPTuners]

I should have something early next week, i need to know your cable serial #

[killerjuice]

I pm'd you my serial number, I also just emailed support@hptuners the link, my file, and my serial number, thanks

[killerjuice]

well that was really fast, the update is released 9 days before I even get home from work.. so things are looking really good and I will post my results when I get home... thanks alot Chris and Keith

[Chris@HPTuners]

does the amount of timing you are seeing correspond with the numbers in the new table? if so, then i think that will solve it.

[killerjuice]

I will only be able to tell when I get home and driving my car. That table looks like those are the exact values that I am dealing with now, so I am more than 99% sure that this is the exact right table. Thanks again, I will keep posted.

Was this an issue on any other OS's besides the GMSC 2.4? Are NA LD9 OS's affected as well/updated as well? Great work guys!

yes once these guys test it there will be an update for all early 4cyl vehicles.

This update works great. Now I have complete control over the timing at WOT. Now support needs to get us some more control over some of the other things.
