19 Jeep 3.6 w/ Ripp supercharge - part throttle knock retard and misfire codes?

[GrannySShifting]

Didnt pull any timing on dyno WOT really - later found out it was on 87 octane. Ran couple tanks through on 93 and its not setting P0300 code immediately like it was doing on initial drive before cleaning up some stuff in the supplied tune, but will still after some days of driving. Logged it recently and I see it at 100kpa while part throttle (like its stock at WOT) and I see knock retard there and misfire counters going up - but WOT no knock nothing on street (was .80 lambda on dyno up top). Wondering if bypass valve is staying shut when it shouldnt be making manifold pressure artifically high? Or need to have power enrich come in there but that would burn a ton of gas being in PE every time you touch the throttle.

You can see misfires sprinkled around on longdrive log, and at 3:30 you see cyl 1 3 and 5 with a good with only 18% pedal (95kPa, 1400 rpm 36 degrees timing) Knock was only showing on cylinders 4 and 6 though? Looks like they disabled the VVT spark adjustment, but I dont have a stock 2019 Jeep cal to put part throttle spark back to there and see if it doesnt do it. Comparing to a stock Challenger 2019 V6, looks like they took alot OUT

its prolly just lag

prolly pulling timing from them all in real life, but you are only seeing what you are seeing cuz of lag

that is the problem with speeding them all up to a polling interval of 0ms

i quit doing so as per Bills recommendation and really started paying attention to what was needed for what i was doing and their order on the list

like pedal for instance

there are 4 or 5 channels you could delete and replace with relative pedal

its a lil wonky on these newer cars, not the 0 to 3.84 that you might be used to, but it is quick polling and accurate

I didnt select any polling speed, thats whatever it defaulted to. Recommendations on what and what to set to?

Which channels would you delete? How does the relative pedal work vs?

[GrannySShifting]

Polling interval is 500ms on Misfire History, Knock Retard CYlinders is 200ms, so im not sure what your talking about?

And also... what would make it show misfires regardless of that

[GrannySShifting]

Noticed that misfires ONLY show heavy on cyl 1 3 and 5
Also noticing when it happens, the intake and exhaust cam numbers are low and very near each other

What does the intake and exhaust cam center pos in degrees actually mean? Like if intake is around 95 and exhaust is around 80 where is that in normal cam centerline degrees Im used to thinking in, and is that retarded or advanced for each lobe. Its almost like its in a EGR overlap thing doing it, but why only one bank would not make sense. But in all the logs, the intake has to be below 100 and exhaust below 85 or so for it to do it??

The cam position is shown in centreline degrees like a "normal"cam.
So the really low cam centreline numbers mean lots of intake advance and exhaust retard....so plenty of overlap (mainly for egr).
Blower engines dont like that much overlap so I usually recommend a MIN of 100 on either cam.
Optimal is usually bigger numbers than that (even moreso with a PD blower).
This will also calm down all the crazy cruise kr that you are seeing and the misfires too.

My gladiator 2021 sitting at idle, cams are at 140 and 120. its all stock so far accept for some cooling bods, radiator, trans cooler and oil and trans pans. 180 tstat.
just an fyi. jeep runs alot better after a tune. feels like your in the backseat of a cop car going to jail...

For a 100% stock NA 3.6, the Part throttle MAP during light cruise is >80-90kpa. So you're 100kpa with the Ripp isn't that note worthy especially if the you left the Valve timing alone.


0 Knock on 87 octane is disturbing. Knock should have been quite pervasive with shit fuel ,Boost and 11:1 compression.
