Strange Ignition Values??
 

I have a wolfv4 on a nissan 4cyl turbo engine. I've noticed recently after a drive with a bit of full boost when i check the datalog (the poxy min/max one on the h/c) the minimum ignition value is -11degrees!! But there is no such igniton value in the map. When i reseted the datalogged values and then go for another thrash i didn't get such a figure (min 22degrees instead).

Any ideas where its getting this value from?? I'm getting a missfire on boost that seems to come and go. I'm kinda thinking its plugs and/or coil but could it be for some reason the ecu at one instant is retarding the timing?? When it misses a lot of smoke seems to puff out the exhaust. I tried turning the boost down one night when it keep missing on boost from 12psi to 8psi but it still did it.

I'll check my plugs this weekend and change my fuel filter, but the fact that its intermitted suggests its not the fueling.

If you use the beta version of the 4.72 software it changes some points randomly so you could have a point at -11 on the map (or 0 hex in the map for those who like raw data).

HMM I don't think i've used the beta version. I have the latest one but i'll check the map anyway.

which one is the beta one? how do i tell the beta version of 4.72 from the non-beta version?

Yep I know.... it works properly:rlaugh: Look in the help >about and at the top it also has the revision 1.5 is unstable.
