202402 Firmware update and some problems #30

Open h25r opened 6 months ago

h25r commented 6 months ago

Hi! I updated to latest speeduino stable release, and compiled to 6 injection and 3 igntion channels but some things dont work well

PWM fan didnt follow coolant temperature curve
CAN inputs vss 1 to vss average dont work well
VVT1 output didnt change to desired degrees and enter in fail mode
Maybe other problems that i dont know because downgraded to a working firmware.

Can someone compile a working version? I dont know if pazi will continue updating firmware .hex folder

The PWM Fan I know to be problem in the 202402 FW. Something to do with the changes to how secondary serial works. I couldn't figure out fix for that before the FW came out. Others are something that I haven't been able to try, because I currently don't have board/ecu to test. I sold my last car with speeduino...

I would be happy to be a beta tester for any version of the new firmware.

I'll be attentive in case you release a new version.

I hope to try your new build this weekend and report any errors I find.

I can confirm pwm fan and vvt issues. However I saw no readings for vvt1, and no duty cycle applied to either solenoid.

Flashing back to 202305 and it all comes right back. Same tune, no changes.

I hope @pazi88 pazi upload some firmware that works when he has time... Maybe some beers via paypal will help!

The bugs are really speeduino firmware thing. So if you are finding issues, please report those on Speeduino github. With logs and such @williammueller @h25r

ok i got firmware 202405 working now, changes made from noisymime also i made new bluepill version to allow it reading %duty values from the right location (new version moved it from case 121 to case 123)

I upload here the .bin to fix bluepill on newer firmware (also changed minimum pwm duty from 10 to 5%, my fan can stop now with values under 10%) 202405bluepill.zip

Sorry for the late response. I can confirm building from 2024 fix pack 1 matched with the @h25r blue pill firmware appears to work smoothly.

@h25r Could you provide the raw code you used to build that firmware with the fan controller fix?

changes made to serial3tobmwcan.ino

line 173: Serial3.write(123); // LSB offset for receiving PWM fan duty. line 771: if (tmp_duty < 3){ // adjust the range to valid 10-90 for BMW fan line 772 tmp_duty = 3;

sometimes fan stay off until reaching the 10% value from speeduino and other times spins at minimum speed all time its enough for me but there is some more research to work perfect.

@pazi88 maybe you can add that version of bluepill to bluepills folder so anyone can update speeduino firmware version with that ecu
