I have the same thought.

The rest.. like no mod only..

It's not designed to 'retune' itself back to the original setting. If that's the case, it's suiciding. It's designed to adapt to the new input parameters (if any), and making adjustment so that the control output falls within a predetermined range, for reliability and emission control.

If the ECU keep resetting back to base map, it's either teh car or the ECU has a problem.

Yes, 4G18 is running on MMC ECU.

Which Siemens VDO are we talking about?

EMS700 in the Campro, or the EMS400 in the 4G13/15/93?

It's using a Campro S4P, so EMS700.

Dastek Unichip, Apex'i SAFC, Hydra EMS, even Greddy E-manage.. all work well on it.

There's another option for Siemens, Works EMS-1. about RM1.6k also. Compete with harnes and software if not mistaken. I may try this.

Difference between EMS400 and EMS700.. a lot. will elaborate more next time i post.

Forgotten to mention, under light load (low TPS signal vs RPM), it's close loop. Once you step more on the pedal, it goes open loop, and that's when the piiggyback will work.

If the ECU can handle the optimum A/F for economical driving, let it do the job. Piggyback takes over only when you want better performance. This, to me, is just ideal.

Both SVDO EMS400 and EMS700 can be remapped and retuned. But only Proton knows how to do that.

Increasing the idling speed is not tuning and it's not worth any cent to so. Just clean the TB and let the car idle for 10 minutes, then drive like normal for two days. If the problem persists, the TB has a problem, and "tuning" will not help.

The core program are still intact even with reflashing. You only change the mapping by reflashing but reprogramming can do even more.

somehow, someone did it with Proton engineers from the R&D.

I do not really know.

MUT or PDT2000 are ECU scanners and diagnostic tools use by Proton.

Auto transmission?

it will not go above 4k "no matter how"?

clever!!!

Find me a distributor for EMS400 or EMS700..

unfortunately, mitsubishi.

For the Wira 1.3/1.5, GTI 1.8, old Campro and Campro CPS - ECU controlled coil pack, with ignition cable. The coil pack looks like a distributor anyway. For Campro IAFM, coil on plug.

Sorry.. except SAFC Neo.

Siemens VDo is not 100% close loop mah...

SAFC Neo can't work because the type of sensor it's supporting doesn't match with siemens VDO.
