My Idle threshold is 8160 rpm. From the description, under this rpm threshold idle timings are used. Am I correct to change this to something like 900 RPM?Screenshot 2024-08-16 074202.png

HP Tuners has no idea what that scaler is for
mislabeled
do not touch that
*what are you trying to get it to do??? (or stop doing)

Just going through everything to make sure everything is correct before adjusting AFR. Noticed that this was maxed out and read the description and thought maybe I was being affected by it. I was going through my log though and noticed it was 1696 rpm before and I don't recall touching it.Originally Posted by LilSick
Set threshold to 896 and nothing blew up so it should be fine to adjust
right...
i only adjust something when i am trying to get something to happen that isn't happening, or to make something that is happening stop happening
whatcha tryin to do here???
I'm planning on adjusting my timing advance after my AFR has been set. I was looking around and saw this as I was worried that if the value is maxed it will use the idle table instead of the main spark table. Its still set to 896 rpm, havent had any problems yet when data logging. I do have a knock sensor installed that gives readings to VCM scanner as well. What are your thoughts?
first off timing seems to effect volumetric efficiency, therefore it effects your required mixture, therefore it has to be set before you set fueling
secondly, jtec controller (that is what you are using, right?) does not reference the main spark tables lol
dumb huh? thx hpt.
spark on jtec references the idle table when off the throttle and the warm spark table when on throttle
what version of the suite are you using?
Attachment 150942
actually mine might have a different os than yers
its a mopar performance controller
has a os ending in MP
97JeepGCManV7 Fuel DFCO OFF and smooth adv Forced Open Loop AFR V2.hpt
Heres my tune so far, however I have not uploaded it to my jeep yet. this one is Forced open loop and I zeroed out most compensation tables like Power enrichment and part throttle enrichment. I also lowered my MAP based warmup table so that once it reaches operating temp 80-85 celsius, that it would stop enriching. This would put more emphasis on the main fuel table. During my logging my spark advance does match up with my main spark table quite well, I used an excel spreadsheet to see the ratio between commanded and actual and it was fairly 1:1 except.
yeah i don't know... i don't tune like that...
you are making a bunch of changes without testing any of them
when you finally write it if it happens to stumble or surge you won't know which adjustment(s) might be causing that
cuz you won't know what any of your adjustments did
Sicko, your attachment doesn't work.
Interested to see your MP OS.
If in doubt, multiply everything by 1.1.
i'll email it to you Dennis
sicko ha
thats fucked up
why arent png files attaching with the reg link?
i had to go adv and into manage attachments
Did a few runs with the tables zeroed out. The first run definitely ran leaner without the adder tables but brought everything back up on the base fuel map. Overall everything seems to run just fine, no surging or dips besides when letting the clutch go. My one concern about adjusting the map based enrichment based on engine coolant temp is how it will react to negative ambient temps in winter although I didnt adjust the map all that much.
I went ahead and added 1 degree advance in my operating range. My max advance is 44 degrees but thats at higher rpm and dont see reaching that anywhere else. Im not really interested in running 91, would running 87 and tuning based on that be better or tune for 91 and the drop the advance down?
I was just going through my tune and saw the air enrichment fuel correction. This table starts at 82 degrees celsius! during datalogging i can vary from 30-50 degrees celsius during this time of the year. However during winter it can get as low as -40 celsius. Can anyone chime into whether this table should be adjusted as it makes no sense for it to start at 82 celsius
table 34040 should offer approx 20% additional fuel when the intake air is at 0 deg C
about 25% at -40
and no correction (1.000) around 80C
Thank you! I made the adjustments to the table.Screenshot 2024-09-06 074529.pngScreenshot 2024-09-06 074538.png
did you notice a change?
