I have no problem getting an engine to reliably reach beyond 8k, but I still don't know how "fast" the PCM will go.

Since you're an old timer, maybe you've run into Mike Blackstone at NHRA races? ...

Thanks for the reply, but I'm still not getting a feel for the 'speed of light' of the E38. What is the highest RPM anybody has reached reliably?

Jeff

Title says it all. Assuming I build an LS engine that will spin to 9000, will the LS3 PCM operate up there? What limit have you guys bumped into?

Jeff

Yes, writing cal only. The weird thing is that I was in the middle of a very rapid tweak/flash/test cycle because I was working on an idle problem. Probably did 2 dozen flashes in 30 minutes when...

The cold reboot made no difference, but I kept poking the start button and the instrument panel woke up and told me to "Service Fuel System". Remember that this started as an aborted flash update,...

My turn. :( After about 2 dozen tweak/flash/start/log/repeat cycles today trying to calm a bouncy idle, the programming protocol stopped partway through, and now the PCM in my '08 C6 LS3 appears to...

Thanks, will do!

So is the LS3/E38 boost-aware OS available? I have a Vortech blown 08 C6 that could use it.

Jeff

Thanks for the suggestion - that makes sense. I'll kill COT and try another log. So far my measured AFR has been in the 12.5 neighborhood even with a flat eq of 1.12. Once I get measured AFR close...

It's hard to get started when even simple things don't work the way you expect. I set my E38 Eq Ratio to be 1.12 in every cell, then went out for a test drive to log 3rd gear WOT from 1000 rpm to...

That makes perfect sense - thanks for posting! I couldn't figure out how I popped a 10 amp fuse with an ALDL connection.

I'll follow your lead, but will have to attach the car's ALDL connector...

Suppose I decide to dial in the MAF first. I have an LC-1 that I trust (logs show that wideband AFR tracks narrowband mV closely during closed loop, wideband is at 14.7 at narrowband crossover...

Had a bit of a scare last night when I couldn't connect to the car. It turned out that the ALDL fuse on my '08 C6 popped. Is there a preferred order when setting up for a scan or reflash? My...

I want to do a quick test with burst knock completely disabled in my '08 LS3 C6. Based on my search here, I *think* I need to zero-out all the values in the Base vs. CylairDelta table (circled...

I built a circuit using one of my injector driver boxes that lets me feed the injectors any pulsewidth down to 0.0ms and any voltage from way too much down to 0V. I can work out the minimum time it...

If anybody wants injectors tested, I have a flow bench. I just ran a bunch of 120 lb/hr injectors today that were *incredibly* well matched. I could almost have pulled any random set of 8 and...

Thanks for the replies! My first goal is not to learn LS3 tuning details, rather it is to find out if HPTuners is going to work on my LS3 C6 right out of the box. I'm hearing that it will. That...

I've been trying to use HPTuner's main competition for the past week to scan and tune my '08 C6 LS3 without much success. I have to use beta software on the laptop and beta firmware on the interface...

Thanks again! So just to be clear, if I sell my HP Tuners stuff (s/n 00000A229G) to a guy who does not have the car that 00000A229G is licensed to, he'll have to send you guys $199 to add his car to...

Thanks for the lightning-quick response, Bill! What will the cost be to add another VIN to my license? I went to your upgrade web page, but the "+ View More Information" link doesn't work for me.
...

You guys didn't have any of this newfangled credit stuff when I bought in (s/n 00000A229G). I've sold the car - can someone else buy a 'transfer' or whatever from you guys to use my stuff on their...

Thanks for the suggestions, guys.

I'm shooting for the -5 to zero range. After 3 successive logs that kept pushing some low-MAP-low-RPM cells further and firther down (smaller values), The next...

About a week ago I decided to get serious about dialing in my '02 C5 with Maggie and long tubes (otherwise stock). I disabled the MAF and started logging to get data for VE table updates, trying to...

I'm on the verge of buying HP Tuners for my magnacharged '02 C5, but I've heard there is a 2.0 release in the near future. Naturally, I'd like to time my purchase to get the most bang out of the 6...
