Thanks for the quick response Adam. I'll give the changes a crack and adjust as needed. I'm definitely keen to head back to closed loop once this is resolved.

I've had to retune my car after installing a more aggressive cam, the last bit I have to fix up is high rpm after starting the car and when coming to a stop. Usually ~2300rpm after starting the car and ~1350-1480rpm when coming to a stop after driving. Based on my logs, it appears to be because the ignition is taken from the main ignition map in each scenario and is quite high, between 28-33 degrees of advance which keeps the rpm high and seems to stop idle ignition kicking in. As the vacuum reduces, ignition retards, rpms drop, the idle ignition takes over and idle settles in nicely. Should I be increasing the idle ignition lockout RPM to capture these scenarios, or is it better to reduce timing on the main ignition map to reduce RPM in these scenarios even though it may affect deceleration when driving? Or have I got it all wrong and I'm overlooking something obvious? Tune is attached. I can't figure out how to trim the log into the relevant segments, it's over an hour of driving, so I've added markers and sections for navigation. Here is it zipped (19mb zipped/41mb unzipped): https://lenihans-my.sharepoint.com/:u:/g/personal/ryan_lenihan_com_au/EUfbloVB511Jg0_UQ9sCBYcBaSaZeyPphkI9I41wAhEl6g?e=H8rlpe Thanks. 230205_469_jaycar run.pclr

Ah I see. Initially I hadn't setup modelled fuel as I didn't have all the data required and figured it didn't matter if I had the car running well. I was just looking into getting the data for the injectors (I'm iffy on the actual dead times). The ECU certainly does something as it changes the display depending on the master fuel setting, but if modelled won't do it either I'll leave as is and change the display. It's more of a nice to have than a problem. Thanks again for the responses.

Hey Vaughan thanks for the quick response. I'm running traditional fuel mode.

Is there a value somewhere that I have overlooked that adjusts the distance to empty display on my dash? Before the G4+ I was modifying the stock ECU on my Mini. When installing larger injectors I changed two values, the injector constant and the consumption calculation to correct the dash display. With the G4+ while I have everything running nicely, the distance to empty irks me a little as the value is way off, reading 999km remaining until just above half a tank. The Link is obviously outputting the information that is displayed on the dash, wondering if there is a way that I can correct the output at all?

yeh, i gave that a go before i posted up. the base map had it set at 500rpm and i reduced it to 150rpm but it didn't make any difference. Adam pointed out over email that the correct place to be looking was the top row of the e-throttle target table. He adjusted some of the figures and I've tweaked a little bit further. The car no longer stalls 9 out of 10 times, but when it doesn't stall the engine speed drops to about 500rpm before jumping back up, so a little more tweaking of the map required but it's certainly on the right track.

Thanks Adam, email sent.

Hi all, I've just recently installed a G4+ in my R53 Mini and was chasing a bit of advice on getting it running properly. It's a low km motor that I've swapped in and at the moment everything is stock except for intake, exhaust, sprintex supercharger and 550cc EV14 injectors. I've made the change to the master fuel based on my wideband sensor, currently running a 13ms master fuel setting. I've also gone through the calibration of the APS/TPS and MAP twice just to make sure I didn't forget to push it to the ECU. When coming to a stop after driving for a while, the motor stalls. Reading through the help files, it sounds like it could be the anti stall or proportional gain tables. Noting that the proportional gain values drop from 1.5 at 60c ECT to 0.9 at 80c ECT, is this the right place to start? As it's not really explained in the help file, what do the values actually correspond to so I can make adjustments properly? Also curious as to how the MAP limit works. I'm seeing a boost cut at 15.3psi (207kpa/3.93v on the MAP), referring to the MAP limit table, it was set at 215. As 207kpa is about 96% of 215kpa, are there settings elsewhere that result in a change to that limit? Just wanting to make sure I'm understanding 100% how it's working before I start adjusting..
