I previously checked the german version of the Mitsu parts catalog. There it was only written that the d22 has the same maf.

Since the eclipse was here available N/A only, there was no restriction between N/A or T/C. That turned out when I checked the US version 8)
The "missing wire" is called MAF reset but I dont know its real function.

Would be great if could check the MAF parameters !thx!

Wideband is here but still need to weld the bung fo installation.

I'm not sure about my values...

There seems to be something awkward going on. According to the EDM NT file I have (E935), the MAF values are higher than the 1G. 231 g/s for MAF size, and the MAF comp values are between 128 and 135. Very strange. The MAF Adder is the same though, 100.

I need to research a bit more. Do you have the ECU part #?

Working ECUs
MD166252_____E33 GTi 90-92___(better than stock)
MD152983____C58 GTi 90-92__(stock ECU)
MD132957_____E33 GTi 88-90___(not tested)
MD169144_____D22 N/A________(worse than stock)

Just personal impressions no dyno based results. I am not 100% sure about the E33 ECU, I think I have the 90-92 one but will check that later.

No part# on my ECU anymore. But should be from a 92 e33

Sorry for taking so long. I haven't been able to find that exact file, but from all the ones I could find, the MAF settings are very close to the 1G Turbo ones. They differ at higher Hz values, due to the difference in airflow from NA vs. turbo modesl, but there's no real difference at idle/cruise.

May I send you my ROM so you can take a quick look. Or would you send me your ROM? Since I am quite new I would be extremely happy if you would help me again ;)
No problem for taking some time, since it is your time ;) And thank you so much for your afford!!

EDIT: Reread the thread and seen that I might mention a small point ;)

The 1.8L Eclipse has the 4g37 not the 4g67 as the 3g CSM with 1.8L. The 67 was exclusively sold in Europe (as far as I know). It has the 88mm stroke like the 63 but a smaller bore of 81.5mm.

The USDM rom (9417) and EDM rom (9653) have different code for different cam reluctor signals, so maybe your CAS outputs a signal that's better for the 9417 ROM. If you get a CEL for the CAS signal, you will have to switch back, since it will run in limp mode if it experiences that error.

I finally got the wideband installed :)
Installed the Evo ECU but was wondering couse the afr was way too rich. It is still stock engine with 240cc injectors but I had to increase the Inj-size in ECUflash to 340cc/min and decreased the MAF size to 222 g/s. Any ideas (known mistakes of newbie-tuners) about that?
The engine was warm from a tour i drove before. So no warm up.

I know it is a big favor, but could som1 tell me what corrections are in the software that should be turned of for easier tuning?
I switched off:
Global Fuel Settings - Accel Enrich
Global Fuel Settings - Lean Spool
Global Launch Maps

Has somebody changed the knock filter for using the stock 1g knock sensor?

Today starting the cold engine... at least I tried. Cranking over but does not fire up. AFR after start reads 14.7-14.8:1
AFR gets no power while cranking - I will rewire it but any idea what I am doing wrong? Or is the 1g maf not good with evo ecu?

Little progress for a long time but I have it running quite well. Decided to change the MAF and threw the 399 and the knock sensor of the Evo in :) The knock sensor since I read that the CSM one has an internal filter and therefor would send a too weak signal to ECU to be processed in a proper manner.
I figured out that increasing the Cranking Primer Initial Pulse makes the engine firing up quite well - since our cars have no FuelPressureSelenoid (FPS) it makes sense. The FPS prevents the vacuum of the inlet to reach the FPR and reduce fuel pressure. The CSM therefor has a lower fuelpressure when cranking ~2,7bars (expecting idle fuel pressure) compared to evo 3,3 bar (?). Will try to change IPW comp starting and if the effect might be better but currently car is alway starting even @ -5 °C

I am using the 96532706 v7 rom. Injectors down to 215 and the car was already running quite well. For safety (and cause I am afraid) I pulled 2° of timing over High and Low Ign Map. After EGR FuePressure and Wastegate Selenoid CELs (deactivated in the periphery bits) I only had the CEL "Coolant temp for Closed Loop not reached" - which is a side effect of disabling the rear O2 in FAA bit1. Switched it back to "1", have the rear O2 heater disabled and the O2 signal emulated and voilá - CEL P0125 is gone.

The only thing left till now is the CEL for P0622 - Alternator F-Terminal Circuit. For that unfotunately I haven't found a solution yet -.-

Didn't try a 9417 ROM since I would like to stay with the 9653 LiveMap version. If anybody has figured out or just might have a clue on how to disable the CEL for the P0622 I'd be glad to gain that precious information :)

I had an alternator code until i swapped out the cas for a blacktop one. That was on a 2g flashable ecu, but close enough.
