Hi guys,

I'm just starting to tune my vehicle with DSMLINK.
It starts with idle, I have 2 - 3 questions.

Short details about my car:
99er Eclipse
2.3 6 bolt
70mm S90 Throttle
1200 PTE Injectors
1g CAS (green)
JMF Race Manifold
LC2 Wideband Sensor
3.5 Bar AEM / AEM IAT (Speed density)

I use the instructions "How to Tune a 1G V3 SD ECM LINK with no MAF
Version - 1.5 By Aaron Ruppert AKA Dr Turbo".

1. Log (cold-idle)
The vehicle is cold and running at idle up to operating temperature.

2. Log (idle-warm)
Continuation of Log 1

3. Log (hot-start1)
I restarted the vehicle. The idle speed goes to 2500 rpm for a few seconds, i dont no why?

4. Log (idle-warm2)
The values AirflowPerRev, STFT, LTFT and ISC Position look good.

5. Log (hot-start2-idle-warm3)
I start the vehicle again for the second time. Again, the revs are for few seconds high?

My questions are:
1. Why are the rpm so high (~2500 rpm) after starting the warm engine?

2. Do the logs look okay to you? The ISC position is only close to 30 in the last log.
I checked the ISC valve, it's fine.

3. The idle speed fluctuates a little bit. I have FP4 Camshafts and 1200 PTE injectors.
Are those fluctuations normal?
The car has not yet driven with this ECU.
I want to make sure the values are okay.

Thank you all.
Pierre

I looked at the last log and it looks solid. I wonder if you should disable hot start enrichment and see if that helps.

I had already tried that, but it didn't help.

Did you adjust the biss with the car running? I think 1g is different but you do it during warm idle in neutral for a 2g.

also with idle set to 900rpm you may have to retard timing
