essb00 is correct about the lack of AFR, but you also idle at roughly 950 with an IAC output duty cycle of 45 but your base IAC output duty cycle is set to 33.... you need to raise the base to match what it actually needs when idling properly. (Idle Base Position Table)

@Adamw seen this?

I would lower your proportional and derivative.... I'm sure adam might have better starting points for a G4+ but I'd test it with .5 Prop and .15 Der

post a log of it happening

AIM dash will not appear under the CAN device tab... only Link items will pop up here.

I don't know G4+ software nearly as well as all the new stuff but your only removing 20% of your timing, and you should turn on fuel trim... try adding 30% fuel.

Anyone seen this before? popped up during a store attempt.

if you haven't figured this out yet, I've seen similar issues when CAN hi and CAN lo is wired backwards to the dash

yes physically re-clock the sensor so that 1-6 are all ascending/descending voltage changes, as Adam said above reverse and neutral can rotate off the linear scale but not the drive gears.

have you done other sequential setups where the barrel sensor rotated back around to a higher volatge? I'm not sure if thats causing your issue but seems likely. does your vehicle speed work? and have you setup the gear ratio table in the ecu? can you post up a log and copy of the map?

you can leave it on if you use a math channel

this is the kind of shit that would waste hours of my day glad you figured it out

I'm pretty sure ethanol temp is not used in the fueling calculation as an actual fuel temp sensor would be but wanted to confirm. If a separate fuel temp sensor is installed it will have an effect on the fuel calculation but not the ethanol temp. correct?

If 4d fuel is enabled and the table has only zero's then it will be doing nothing to change the fueling. It will basically be multiplying the final fuel value by 1

car already had to leave on its way to a race event but after reading Adam's email and learning about a change that was made to the throttle body flange I'm pretty sure Adam is correct. Thanks for the help

ok so if the throttle body isn't the issue I need to look at the wiring.... and I was just testing the reaction with the PID but I was pretty sure it wasn't gonna change anything. I'll look into the wiring, thanks Vaughan

As you can see in the log at the end of the dyno pass the throttle is closing slowly... target drops immediately to zero but it slowly shuts. I've tested multiple PWM Frequencies, modified the PID numbers... nothing seems to help. I have even tested it with a new throttle body with same result. Bosch Motorsports 74mm E-Throttle Let me know if anyone has seen something like this PC Datalog - 2023-04-27 1;35;53 pm - throttle hang issue.llgx

I see what your saying, interesting... I never even noticed m1 was doing that. I see how it would be helpful when the axis is MAP but I think it would be less helpful tuning via alpha n with tps as the axis, since you usually need big jumps in VE over very small throttle changes down low.

the accel table can be 3d,using (tps delta) if they allowed for negative numbers in that table that could work assuming a negative number in that equation would give a reduction in fuel as I expect it would.

are you wanting to be able to use interpolate in the axis setup window?

when you say post start, I assume your wanting a richer target when starting up a warm car? if you are using it for cold start then obviously you could just use the overlay table with ect as the axis, and if you wanted to implement IAT you could use charge temp as the axis instead... I agree IAT could be useful in certain conditions if separate. I like the exhaust temp one :D, I have requested exhaust temp boost target trim. if you did throttle position it would likely need to be a trim target table, I'm assuming your wanting throttle and map to be involved in the target calculations. if NA you can just make the target table axis throttle instead of MAP. average load over a specific time? like around a race track? multi model fuel mode does have 2 target tables And I think the problem they will have implementing all of that is the processing power needed for using tables. If I'm not mistaken the tables is the largest draw on resources for the ecu, I'm even quite sure they have a table limit. Someone from Link can chime in here if I'm wrong. @Adamw @Vaughan

this is what I usually use but math ends up with same result

I would definitely already be doing what koracing just said above, but I have done a few of these and my offset is 70.

maybe someone smarter will chime in but you could blip for up and down shifts, then rev match would work

you can turn off multi fuel and use dual map with a trim knob and just watch the ethanol % on the sensor and manually move the knob where you need it.
