CA18DET - Nistune can't display battery voltage

Post by DeJi »

I sold my old engine (340rwhp CA18DET) to a friend, and he's having some running problems with it, and the only thing I can find so far is that I can't log battery voltage in Nistune. I'm pretty sure I could see that when the engine was in my car. The question really is if this is a bug, or if it's possible that the ECU can't see battery voltage for some wierd reason. Maybe one of the ECU power feeds are dedicated to reading battery voltage, and the harness is damaged somewhere. Sounds really far fetched, I know, but it's a lead I wanted to pursue, cause I'm running out of ideas. If the ECU can't read battery voltage, then injector latency, coil charge time and probably some other parameters would be affected, right?

There was a bug with the earlier 0.10.x versions where battery voltage was not reported to the screen (therefore not logged) but that was changed in the later versions and the logging works for Type 1 board (eg my R31) for battery in the later versions

Make sure you are running the latest version and should be good

I think I'm running an early 0.10.x then cause I couldn't get my techedge wideband to work with the newer one.. but I'm satisfied with it probably being a glitch in the software. Will have to troubleshoot somewhere else. It didn't sound very logical that the ECU wasn't reading battery voltage, but as I said.. I'm running out of things to check.

I've checked techedge again in the latest version. It was only CA18 being a problem with battery since it wasint in the original consult tables when we started selling Type 1 boards so it read in addition to this table
