Title: 1.1.65 problem with Gamma Enrichment (GammaE)
Post by: dnb on January 25, 2010, 07:29:31 AM
I cannot get gammaE to come out sensible in Vemstune or the logs when running on my bench-test harness.

If every enrichment I can reasonably get at is set to 100, then GammaE always comes out at 149%
Things I have done:
*Warmup bins set to 100
*MAT/TPS enrichment set to 100
*VE table (in desparation) set to 100
*Zeroed accel enrich
*turned off baro. correction (always off on the NA cars anyway)
*turned off EGO control

I believe this issue is also present in 1.1.63 and 1.1.64

Is it simply a logging glitch, a bug in the 1.1.6x code or have I overlooked a setting?

Thanks

See my other post about this not working with Prolific drivers again...

Thanks for fixing the enrichment problem though! :)

I had problems with the new vemstune sending my gauges crazy.

I found if I changed the default protocol from SIPR to Megatune in ECU configuration and made sure the Inter Write Delay was 30 the issues went away

Jamo - thanks.  I already use in inter write delay of 30. 

But it's not the issue I'm talking about - I simply cannot detect an ECU at all with the new software.  It looks like the fix for the Prolific USB devices hasn't been compiled in to the new release.  I will try again tonight using a different USB device.

Is the enrichment fix simply a config issue I could get by editing the relevent *.ini file?

I have no problem connecting using a prolific driver after changing the inter write delay to 50

Is this with the newest Vems tune (2010-01-08)?  I have no problem with the last 2009 release.

From when they introduced the inter write delay feature.

Same as my working version then.

GammaE issue solved - it was a problem in vemsTune-v3-1.1.63.ini

The line:
gammaEnrich      = scalar, U08, 19, "%",      1.476, 0.000

Should read:
gammaEnrich      = scalar, U08, 19, "%",      0.99, 0.000
   
It's all fine now without a software upgrade.
