MS2 3.4.0 programmable outputs issue

Post by slow_hemi6 »

Hey all I just changed from 3.3.1 to 3.4.0 and I have an issue with the programmable outputs. I am not sure if it is a tuner studio thing or an ini thing but here is the drama.
I use a programmable output to drive my on/off idle valve. I use my valve as a traditional cold start idle that kicks out at Coolant > 62C but I have a second channel &'ed that kicks it out at RPM > 700rpm. The power on state is ON so when conditions are met it turns the valve off. This set up gives me a throttle kick if the revs drop below 700 which is handy in my car under hard braking or just for things like thermo fans switching on that might dip the engine. Previously I could set hysteresis on rpm to -100rpm. Ie valve comes ON at 700 or less but does not switch off till rpm hits 800. Now if I try that tuner studio keeps changing it to -2 like it has now imposed a -2 limit. that might be ok for other channels but for rpm it is next to no hysteresis at all. It worked fine on the older firmware or rather, it accepted it without issue.

Strange. Moving to the TunerStudio topic so the TS guys can give their input.

Yes, strange.
If I understand you correctly, it is letting me enter the -100 using 3.4 firmware and TS 2.6.19

What version of TS are you using?
Can you post and msq?

I am currently on 2.6.14 and it hasn't asked me to update recently? usually it does for a new version.
Anyway looks like I may have posted too quickly as it seems to be retaining the -100 for me today. I have been having coms drop out issues on the new codes and this has probably been a good part of this issue also no doubt.

There was no auto update to 2.6.19 as there were not significant enough changes to push it to people.
