Re: Nexia with 'RED TOP' C20XE

Thanks. I will try some settings this weekend, from other configs. (Online "archive" ) Maybe one wish or hint for accel enrichment strategy ... about MAX fuel value ...

Re: Nexia with 'RED TOP' C20XE

I found these pages sometime before.

It looks little bit outdated.
and some description for "numbers" Length Cycles, Accel Threshold will be helpful.

I have no idea, if it must be 0.55 or 1.74 or 34.578 ...
(need some hint for these settings)

Nexia with 'RED TOP' C20XE

So ... I need to help with my current config. Engine "cutt-off" on drag race, when I'm shift up, and I can't see why.. (tps 100 to 0 to 100) Can anybody help me explain why..?? RPM, VE, TPS and other things looks good in log. (due to "over-fuel" .. or why ..?) Drag race start at aprox. 260sec Thanks.

Re: rusEfi own wide band controller board add-on using CJ125

I think things are not promising for rusEFI CJ125 unless we known some OEM ECU as a source for used parts? Not many "stock" BOSCH ECU has this chip . ... And another reason for "not to use old chip" is .. LSU 4.2 and LSU 4.9 sensor capability. Old versions is for LSU 4.2 only. No "mark" or "chip nu...

Re: Sprut - A newbies try to design an ECU

The best way to do "the self learning ignition table" is measuring "in cylinder" pressure.
(we need to do measure and recognize unneeded spikes during "fire cycle")

Other ways are angular acceleration measurement and/or Ion-Sense.
