MPPS V16 failed to read Renault Laguna 2 ECU (solved)


MPPS V16 failed to read Renault Laguna 2 ECU (solved)


I just got an MPPS V16 ECU tuning interface and installed it on my Win7 laptop.

I connected to my Renault Laguna 2 1.9dci. Ignition on, I can get an ECU ID successfully but when I hit 'read' it gives a error and tells me to check the log files (which seem to be in Chinese).

Any help with this one? I've read some VWs for example need to have a fuse pulled. Some suggested me doing that by MPPS would lose injectors codes.Better do that with BDM.

 I don't think injector codes are used on my car, I have a 'sonde Renault CAN Clip' device and injector codes are set to off if I remember rightly.

Also a quick Google suggests BDM needs the ECU open on a work-bench but I'm not doing that. I just want to remap for a bit more power I'm no expert so will pay someone to do the adjustments. What's the best cheapo tool to read my map and then get someone to adjust it and write again?

Another suggestion was Fgtech galletto v54 or reworked Kess v2. Somebody has done it many times. But i do not want to spend budget because I do have other cars to tune.

In the end I tried an MPPS V16, KWP 2000+ and and MPPS V13. I had success only with the MPPS V13 - the cheap one that comes built into the OBD plug. Map looks good and safe, stage 1 map

mpps 13.2 run good on laguna 1.9 DCI 100 protocole is wrong ( EDC15C2 ) for edc15C3 but read and write it's ok. tested good.

I extracted my original map and then sent it to someone to have it adjusted for more power. I know those remappers are frowned upon but this guy was based in the UK and seemed trustworthy.

Actually his first remap didn't work and he did it again in another software which did work. He said "WinOLS on this occasion being through is a bad thing....Ecm / swiftec rules" Whatever that means!

I'd be very happy if someone would take a look at the original and new map and tell me exactly what was done and if it seems like a good map? Anything that could potentially be improved further?


Personally it feels like there is a bit more power in the turbo boost range but could still gain more in the low rev range below 1800RPM. No smoke there even foot to the floor.
