Two closely Successful 2 hour drivers on FreeEMS for the most part.
Issues I have currently.
1) MAP reading, its all over the place, I can't tune correctly without a stable reading.
2) RPM reading, again its all over the place at a stable rpm on the tach and on the boost controller, which comes off the fuel inj wire for rpm
3) Rev Limiter, its antilag, seriously I bet I started building boost around 6500-7000 revs
4) Some issue happened trying to go into boost, sounded like a misfire, I was around .7 lambda when it happened, have a 70MB datalog with it in there but I didn't see anything odd or off. timing was at 15 degrees which should be fine. I can check plug gap which I think is at .044 but even so. MS2extra has pushed these coils at 5v with mixtures in the .6x lambda range down a quarter mile without misfire.
around 5.1 -5.2 dwell on the coil
5) Hot Restart, super lean at restart if left a lone for 20-40 minutes and come back to car, like 1.3x lambda lean, normally .94 to 1. I talked to fred but I disagree completely with using the IAT table for this. I have a theory this is being caused by fuel temp. I use afterstart enrichment to fix this on ms2extra. IAT for SD should be used for what it is needed for, changes in temp effecting fueling, which I have seen, A colder day will require more fuel than a hotter day. I don't know how right now but I plan to throw a temp gauge in the fuel rail\fuel line somehow
6) tuning software, The need for good tuning software, it doesn't need super tons features, it just needs the stuff to make one person in the car be able to tune with minmial issues
7)Decoder offset, it seems it is 360- what I had in ms2extra
I have 135 in msextra and around 225 in freeems\emstune
No boosting will be done till 1 and 2 issues are figured out
1)Now once I got it to a point where I could drive with fueling around lambda, she drove great, she starts miles better than on ms2extra, for the most part before one crank rotation that I can tell she fires up.
2)I did notice in batch fire its using two shots of fuel instead of one.
3)I also noticed that with the proper dead time\offset time\etc\etc the changes in voltage from turn stuff on and off, the fueling is rock solid. I turned on lights and blower at once and it didn't have a hint of change not even engine note changed, wideband stayed at the lambda reading. Trust me, it matters when you are trying to use 1000cc injectors on a 1.6l 4 cylinder
4) It just felt amazing to see the Jaguar board with FreeEMS firmware running the vehicle with a long drive and me sweating from the heat of south ga.
I have several things to work on still, warm ups are too rich, VE table needs checked, recheck timing to verify.
You can see how bad the map reading is, its likely a software issue. I did try filtering with a fuel filter inline but it didn't help much. I could try changing locations of where I come off the intake from. In ms2extra I have it filtered with 40 in the field for it, same location same sensor, a lot more stable than this is showing.
