mpps clone and vectra read

[pablo1971]

has anyone had anyproblems with vectra 1.9 cdti 120bhp 2007..

ive done a read and the file size 2097kb..the file is too big...i want to remap this file,but just a bit worried if the mpps hasnt read it ok.then it may not write it ok and i will then have a no start....just wondered if anyone has read this ecu with mpps clone...

Mpps has problems calculating checksum for EDC16c39, so your car will probably not start after remap...

[pablo1971]

oh right,i remapped a vectra 2006 1.9cdti 150 not long back,and ive just looked at the file size,and the 150 is 1048kb ....weird...i guess mpps is not the best for vauxhall

2006+ vectra is edc16+c39 with mxb 2mb flash the read size is same as many I have done with original

[pablo1971]

so what you are saying is that the file i have is a full read and is good to modify and re flash....


lokking on the pc....with the file in a filder the screen says 2048mb...which is good....but if you right click and use properties then it says its 2097kb...weird....

[TribesMac]

Yes file size should be 2Mb, but MPPS cant calculate checksum for that ECU... find something else...

[pablo1971]

tribesmac,thanks for the replys....is this from experience.as i dont really want to lock the ecu up....

I read and write succefuly Vectra C 120 HP with MPPS, the file was 1MB.

[TribesMac]

If your file is 1MB then you ECU is EDC16C9, not EDC16C39. MPPS has problems with EDC16 ECUs that have 2MB file size.

I have no idea if this is fixed in newer software versions, but with 3.0.2.37 I never succeeded successfully writing any 2MB EDC16 ECUs...

thanks for the replys...tribemac---your 1st reply about the mpps not correcting the checksum on a write.i have winols,so i could correct it that way....if i do this,would this be ok to write...or should i get something else to do the write.......

[TribesMac]

No, it doesen't work even if you correct the checksum in the winols... I tried it on a few cars, it never worked. But luckily I was able to write back original file, and everything worked fine. Then I used different flasher...

[pablo1971]

thats nice to no,ive always wondered what would happen if you did a correction on winols.

the mpps does say that it corrects on this vauxhall...so is this one of the glitches on mpps....
