Syvecs Forums

I think we figured this out. Turns out the ECU was not grounded properly and everything was off. Vbat was off as was the map sensor. We grounded a power ground to the old ecu bracket and everything is reading normal, wherever the syvecs was grounded before (loom im presuming) had some sort of impeda...

I'm using pin 42 (off the top of my head), it's one of the AV inputs and is configured for 5v and I have used a linearisation I found on this board for the LC-1 which matched up perfectly with what my gauge tells me at various voltages. The gauge is fed from analogue output 1 from the LC-1 controlle...

Has anyone previously used the 0-5v output from an LC-1 controller to feed the syvecs a wideband signal? I have tried to do this and have used an AV input to do so. This is working however it reads approx 1volt lower than what the LC-1 is outputting. This results in the afr reading roughly 2 points ...
