HI

I a first time user of VEMS and am applying it to a Mazda LF 2.0

engine with COP and Throttle bodies from Nissan Pulsar Gti-R and hame made extractor exhaust. All this in a Locost super 7 and now fitting a Rotrex C38-81 compressor to reach 300 hp.

Ran it with some help this summer from a local installer who helped out to get the basic map in place and it ran fine for a while but I had connected the generator wrong so I had no battery charging, and this made the battery go flat while we were mapping.

All of a sudden the TPS went dead and what I can see the 5V is not coming out of the EC36/pin29 (and pin28)

Need help with this issue now during winter since the acceleration enrichment is not working.

Thanks for some input on this issue.

I bought an unused system from 2012 with board version 3.6 and full harness from VEMS.

I run 4 COP with waste fire and haven't connected the Cam trigger yet. I'm running WBO to be able to map from Lambda. The system has a built in MAP sensor at 400kPa and 2 knocksensors that are not connected. 8 IGBT and LCD display to keep track on things.

The system is working fine except the 28+29 pin on the Econoseal 36 at 5V. I have tested the output from pin 28+29 and only very low,0.13v, is comig out of the box.

I think the 5v dc regulator has been broken.

Could the loss of power and no battery charging from the generator have caused something in the box to break?

-This is the problem -they do not work OK and TPS is dead.only getting 0.13v from both 28&29 so Ithink the Voltage regulators inside are dead.
  • 5V is easy to regulate externally, or acquire from the "PS2_5V" 4 throughole pins next to the processor (only remove endplate, no need to unclamp TO220 clamping plates)
-I don not want to fiddle around inside the box because I am not that capabel around electronics.

Mounting the Compressor I'm gonna need the TPS and the ability to enrich the mix at acceleration.
