Title: Help! No spark! It was working fine till Now!
Post by: alfasud on October 04, 2019, 03:11:10 pm

Hi all, we have some problems with our Saxo: PNP ecu, was working proparly, but we tried the ecu to another similar car ( 106) and since then it apears than we dont get spark any more...
We also observe e "Less Pr. Trig" led flag in the Log.
Here is a cranking Log:

For a moment we thought that may be ecu has some problem. Is it possible low voltage during crank to make some damage to the ecu?

We really need some help on this!

Best regards and thanks in advance

It apears that problem started just after we uploaded an older config we had. That config was from another vems ecu, older firmware and older vemstune.... Is it possible something went wrong with that?

Yes you best have a good look at the settings as they where before and now after to identify differences.

Thanks for answer!
A circuit was found dead...It was replaced and now ecu works properly... :)
