Hi,


I`ve got a Problem with my SD Convert too.
I`m on 96531706 Tephra, EDM Ecu with Spoolinup Harness.


first Startup was no Problem but the car was very lean in idle.
I increased the "SD RPM VE" table, from 100 too 145 to get my AFRs in a good Region.
(is 145 normal?)


but my AFRs are jumping from 14 to 16. not very stable.
also if i open the throttle it does not feel very smooth.


any idea what could be the Problem?


my log:

Did you start with a fully warmed up car or stone cold car when you tried to convert? Also you need to be logging stft and ltft to get an idea of what the ecu is doing to keep the car at stoich.

 

I started with a cold engine, but on the last log the oil was already at 60°C and water was already warmed up.

But the tables I adjust to tune stft and ltft is still the rpm ve table? I ask because I'm at steady throttle openings and the afr is jumping.

 

You tune stft and ltft by adjusting injector scaling and injector latencies.

Are you converting from a good MAF tune or did you just do a bunch of stuff to the car and are starting from scratch with Speed Density?

 

Starting from a good tune where injector size and latency was setup and worked great.

 

That's what I was thinking but just wanted to make sure. You have something inputted wrong somewhere then. You setup for OMNI 4 BAR or whatever you're using right? You should have started rich and safe around 100 RPM VE and had to lower it to get AFR in check.

 

Had some time today to work on the Evo... Problem found, I dont know why but I forgott to copy the latency table.

Thanks guys!!!
