OSE 12P V112

yeah just realised that and uploaded them with v1.09 labels etc

Ive got an old go kart with a 500cc single cyl 4stroke motor bike engine and i am thinking of running delco 808 on it.
Im wondering if anyone has done a single cyl conversion before.As 12p only goes as low as 2 cyl i was going to put a trigger on the crank so ecu thinks its a two cyl ,and the extra spark would be a waste spark,but it has points that run off the cam and i would rather use them as the trigger as its heaps easier.
I was wondering how much code would have to be changed so that 12p can run on single cyl ,if its not to hard it would be a good addition to have for $12p

It could be added although I am not sure how well it will work due to the accel changes at low RPM. The RPM logs from jayme showed some pretty severe saw tooth on a 2cyl so would imagine a single cyl to be even worse. The spark was def not stable either so might have to switch to module mode at low RPMs.

If its not to much trouble to add ,i would like to see how it would run ,and as you say if est was unstable at low rpm ,just use module mode till 1200 rpm
thanks

Ive also got a 6.5 kva single cyl 4 stroke generator which runs at 3000 rpm - which would suit 12p 1 cyl , could be the first delco powered generator .

Would be producing heaps of current just to drive the injection system

The 808 PIS firmware may be better suited as it can do alpha N and I believe 1 cyl. Although the developer has gone quiet so not sure if the project is still alive or not.

[vn5000]

Yeah that pis software would be good but i cant get it to communicate with a pc

[VL400]

Sorry but due the code structure getting 1cyl is a bigger task than I thought. All the cyl select flags through the entire code work off 2 bits (00=2cyl, 01=4cyl, 10=6cyl, 11=8cyl). Adding another flag into the mix aint that hard but it means another byte of RAM is needed - currently there are zero

[vn5000]

Yeah no worries , ill give it a go tricking ecu that its a 2 cyl.Should work just as well but it will just have a waste spark.
Thanks anyway

Anyone got anything they want added to 12P code? Or any corrections?? Am just working on a new release that has these changes so far...

; 1.1.1 -
; Code Changes
; Removed Startup coolant value as its unused
; Cranking input 0-25.5v Analog input now saved and will be the new 0-25.5v input (Pin B2)
; Renamed spare 0-5v Analog input B12 (was incorrect as 0-25.5v as previously documented)
; Flex table digital option for relay driving
; ALDL Changes
; Replaced Raw MAT voltage with Pin B2 A/D Voltage
; Replaced transient fuel with Async PW (will now see it update during AE/DE)


Am also looking at having a mode 1 message sent out automatically when Pin D11 triggers it.
