LOL - I will return your good news - with some more....
Its ALIVE I tell ya - ALIVE...
Thanks very much, we have just got the worlds first Rover T16 Speeduino powered car running, brilliant work - decoder works a treat.
I chased down some bad earths to the starter motor, and got it turning over quicker, and set my running offset to 10 degrees for now, to try to get it running a bit better ( want fixed angle to check timing when running ).
But she kicked into life - now it does sound rough or RUFF, whatever you prefer lol - but it is alive.
The decoder is very, very close to complete now I recon, the cam sync seems to be very reliable now.
NB - I will check at higher rpm later, as It would not be safe to do this yet, is there still a <6k issue in the code or is that gone?.
Next:
I will try to dial in the ignition advance properly, then Mike I will pick up your new code update, and try again, to dial in ignition trigger. ( we recon is should be around 10 degrees now ).
Once this is dialed in, I will try to get it idling - as currently I have just jamed the throttle body open a little but if I can get it to idle correctly at say 5 percent throttle using ignition timing and get my fueling ok, then I will try to add the IACV once I know the rest is dialed in correctly.
I have attached the running log file, running at the 360 trigger, and (5 cranking , 10 fixed running ). It does run at both 5 and 10 degrees running, but sounded better at 10 ). Note the MLG file is again renamed with *.txt on the end to allow it to upload.
The logs contains some different load points of the car, and it responds ok, so far ( early days ).
I defo have not lifted RPM above say 2k at moment, as it sounds like we are massively spooling the turbo up ( like launch control ) lol, as its running at 6 - 10psi even at around 1-2k rpm speeds ). I hadn't set the duty cycle on my external boost controller, so I may disconnect that for the moment, and let the wastegate just keep it to the factory 9psi max as I dont want any head popping accidents just yet :p
It appears to be running lean, at the moment, but then again I have no AFR closed loop enabled below 1200 rpm where it spends most of its time at the moment.
Once I get the timing dialed in at idle, and we are sure its correct then I will proceed up the table lol.
I have narrow band O2 that I will try to add to the log file output also - just to make sure the calibration is correct on the WB controller.
Regarding the VE table, I see that it has a scale up to 100kpa ( is this not atmospheric pressure normally or close to it? )
My question is that you can see I am around 90kpa unless I press accelerator and it drops quickly and picks back up.
Is my scale correct for a boosted car)0-100kpa) which will be running up to 15psi boost?
Its just if it thinks that 90kpa is under heavy load at the moment you can see from the TPS values it was really at 0% - 5%.
Might it be better to base the VE table off the TPS initially, I am not sure the best way to setup a brand new tune, if there is any good reading I should do, or videos to watch on best way to start a tune from scratch - it would be handy.....
If you have any ideas of what else looks wrong in the logs, and any other areas I need to fix or look at before progressing let me know.
