Old issue, no solutions found. User since 2006. New version 2.42 to 4.11 did a firmware upgrade to #121 without my consent, or i would have refused it. Now MVII license is lost. Unit will not...

Thanks everyone for your input, here's the plan:

1. I didn't copy hi > lo timing tables. Need to rule if KR switched in to old lo timing tables.
2. IFR vs voltage is ok for the 60 lb injectors...

Here it is: 2006 Z06, build LS2 427, 11.75:1 comp, LS7 ported heads, large cam (254 intake), 100mm TB AND 100mm MAF, headers, 60 lb inj. I've logged KR and logged KR continuing to subtract 50% of...

I just put a set of his in, and all the datalog results were identical. Just set them up as he suggests. Very easy.

First dyno test:

Here's a hint of things to come.....

You could also filter

[PID.6310]=0 OR [PID.6310]=2 OR [PID.6310]=3 OR [PID.6310]=4

It takes a few tables. I inverted the FIAF (final idle airflow min) high < 800, and really low > 1200 with a rapid slope. To avoid runaway throttle. Maxed the ETC scalar. Increased the min eff...

You're working too hard. Why not simply scale the voltage table instead?

Since you asked, I got curious. Yesterday's datalog times power ratio of engine no. 1 on dyno yields two results, 595, and 640 rwhp, the latter being more dependable. It is also supports the design...

It's my science project, self engineered. No dyno results yet. Cam is 248/267 .651/.613 112+4. 12.5 SCR 9.8 DCR. 93 octane E10. Heads by Richard at WCCH block by Steve at RED. Dayton sleeves,...

hmm. I could use that. Just apply TM lower RPMs for now

Just 2006 to 2009, which I got off the archives here. Is there much of a change in 2010?

Trying to make a powerful road-race n/a LS7 engine drivable under low-speed conditions. The problem is compounded with the light reciprocating mass engine, a 100 mm throttle body (with weird LS1...

wstaab is right. You were just lucky after the cam. With less mass, now you're not. It gets worse the more mass you take away. I'm surprised your idle is so smooth with your advance seeking...

I'm interested too, as I'm bumping close to that limit n/a. Nothing explains why you have such a sudden fall-off in your curves. :shrug:
Check this out:...

Even on a 11:1 I got 20+ with 2 gal 100 oct/tank. Watch your KR, it'll burn it!

The ETC Scaler is not the problem. Among other settings, I set my 102mm TB to Effective Area min = 50 more or less.

Increased dwell will do it definately. I hear you didn't start out there, but you made it worse.

Anybody have a speedo fail to "0", just to return some seconds later? Happened three times on me. ALWAYS turns on again downshifting to THIRD! (WTF?) The HUD, speedometer and OBDII output (see...

TPMS: Get a small PVC 4" pipe, put 3 sensors in, use the 4th as an access to outside air. Pressurize, put in trunk, and forget.

I had the same problem with a Fidenza dual disc and big cam. Solved it mostly using the VE correction factor table. Where is this proportional table you speak of?

For short tests I try these things out and log a track run or dyno, then back off where unproductive or see KR. VCU is E38. Fun to experiement.

OK. Reason asking is because v 2.0 put them in the program directory. 2.22 changed that. Odd. Maybe it's Framework v2 or Installer v3.

I just ran + 3 ms this weekend and similar power except at 4000 RPM +/- 500 RPM, where it netted +3 HP. That being said, As I understand it, you can increase timing. So next experiment is to bump...
