I have contacted the manufaturer of the TinyWB and he said that my problem is lambda controller hardware related. He will send me a new one after holiday, but thats 2more weeks and in 3weeks this car needs to race on a rally stage.

So, i have borrowed my friends AEM UEGO lambda display, with analog 0-5V output. Can i connect this to the Rev2.2 board somehow?

Maybe an analog input in the 16PIN on the back of the ECU can handle this? What settings i need to change? Thanks in advance.

Yes there is O2 input at the 16pin connector. Just run signal wire (and signal ground to it) and configure it as ego sensor in TS.

Okay, thanks.

I have a good new, V3.0B is ok.
My problem was due to a very bad TS configuration. Difficult adjustment on TPS mode, my set up with N54 intake and big throttle body does not help.
I used MAP mode, and i made a lot of adjustement.

There is one thing i don't understand, in full thottle, above 4k, the rpm needle oscillates (on the cluster)

[jonbill]

glad you made progress. I think oscillation of the gauge rally should mean that rpm is oscillating. do you have a log?

[pazi88]

It could be the implementation of the adjustable tacho duration. Try the "match dwell" -mode.

RPM curve on Log is ok, oscillations are only on cluster. I try Pazi mode ASAP

Hi everyone. I noticed a few diodes missing in the BOM for v2.2 . D6 D7 D8 & D13. Is there a reason for them being there , may we omit them .

Those were just in case diodes to see if those help anything. Not there in older revisions. After some testing I have come in a conclusion that those will help, so I now added those to the BOM.

I think I might have an older version BOM . Will check for the latest release. I managed to find an alternative for the zener diodes (original part 1N5919BG Zener : alternative 1n5339B ) it's way to big though so I kind of surface mounted them.
I started the car an idled it for about 20 seconds without the diodes (D6 D7 D8 & D13) as I'm not certain on their part numbers.
Thanks or the fast response Pazi88.
