A little surprise

[GMPX]

Thanks to everyone for sending in the files they have read so far. The good news (for us) is nobody has run in to any troubles and the typical read times are about 12-13 minutes on all three ECM types and year models.
We've had files sent in from all varieties and year models of cars, from SAAB's to the latest Cadillac's, so please keep up the good work.

Cheers,
Ross

Hey Ross, I just had a "Duh" moment! I was so excited about the possibility of tuning the 3.6DI motors I forgot all about another big market for you to tap. The 2.0 Turbo DI motors, or "LNF's". There are tons of guys (me included) tuning LNF's with some other software (that shall remain nameless), but they've been pretty much ignored for quite a while now. (Years actually.) What is needed is fuel control for bigger turbo's and higher hp, plus a bunch of other tables that we know are accessible but the "other" guys don't want to bother adding into the tuning software. The tables that we have access to are extremely limited, it's gotten the LNF's to over 400whp but only with 3rd party tuning on top of a modified tune, sometimes on top of a GM accessory tune. That means some of these guys are spending tuning money in 3 different places to get what they want. I know plenty would be thrilled to have a solution that covers everything, and with better support.

Bottom line is if there's any way you can support these ECM's, there could be a pretty big number of guys jumping ship to switch to EFILive for tuning. These motors with the Bosch E69 are in Cobalts, HHRs, Saturn Skys and Pontiac Solstices. Now yes, I realize these are phased out platforms, but the LNF motor is still living on, probably for a long time in the new Buicks as the LHU with a Delphi ECM. That tells me there will still be motors and turbos being made for guys doing engine swaps, and when the new ECM's get locked from tuning or not supported by anyone the older Bosch ECM's might still be a viable system to use. There are a bunch of people using these motors in sand rails, Jeeps and crawlers, tube frame custom built stuff, etc. 500hp out of a 2.0L will keep a lot of guys using this drivetrain and Bosch ECM for awhile.

I've got 2 E69 files I can send you right now, an '07 and '08 2.0L LNF. I'm sure if you wanted or could use more there'd be a bunch of guys willing to help out with this. Sorry if I've said anything inappropriate in here (mentioning other tuning software vendors), or if this shouldn't have been in the forum but in a PM. If so feel free to delete it and send me a PM.

Thanks Ross!

I'll start by saying that what the LNF tuners want is what scares people away. Bosch systems are the hardest things to work with (that I've come across), I don't know the ME961 systems that well, I know a number of people who do because they specialise in European car tuning and they always seem to struggle too when you get these builds that push the ECM far beyond what the original design spec was. We do need to weigh up if it is worth our time as I would suggest Bosch will be gone from GM's cars in 2012, all replaced by the new Delphi ECM's. So we are really only looking at a 4-5 year run on 3 different ECM types (E55, E69 & E77).
It's easier (and cheaper) to learn from others mistakes, perhaps HPT felt the R&D time they invested in the Bosch DI systems vs sales did not warrant further additions.
I may still stand to be corrected here, but the claim these many of the Bosch ECM's can't be read appears to be proven wrong with our beta release, I have reads sent in from all models years from 2005 through to the latest 2011 cars from all three Bosch ECM types. At some point we will sit down and analyse all the files to see how hard this might be.
But no promises or time frames, we have our 2011 support map already full, these weren't even on it a few weeks ago

If you are going to send files in we would prefer stock tunes.

Cheers,
Ross

Thanks for being understanding Ross, I know the Bosch support request has been a tough one. I'll send you a couple stock tune files when I get a chance. I did read out the '08 this evening, it read fine, took about 13 minutes.

Thanks again!

[GMPX]

Yep, 12 to 13 minutes is about right. It could be faster, but Bosch didn't implement the comms correctly (not the first time with them!)

I just ran across this thread. I sure would like to see LNF support.

I have a 07 2.0 LNF Sky that has the GMPP Stage II tune in it. I can read it and send it to you if it would be helpful.

That would be great thanks.

Meanwhile, I guess the attachments below could be considered good progress for the Bosch tuners amongst you....

OMG Christmas in March! (Or at least a little stocking stuffer teaser!)

Thanks a ton Ross, any progress on this is much appreciated and needed.

Wow, 36 second flashes or am I misreading something?

Ross,

I just read the E69 in my 08 Sky LNF (with GMPP Stage 2 kit). Where would you like me to send the file to?
