just a short update.

found whole heap pf rust on my e30, so fixing that atm.

i think fuel flow is not neccesery factor.

at given speed you have given gear and stable rpm. so they only thing you can tune for is the shortest possible PW and that will give you best economy, doesnt matter what map ...

several thing affect starting....

you didnt give much details.
like what ms you are using with whcih code. fuel or with spark ? crank trigger setup ? what warmup what afterstart settings ? it is only on cold or aswell on hot ?

you say it doesnt start.. it doesnt start at all or maybe it sputters ...

ok, ok, ok... hang on there tiger....

you are saying that tpsacc is actually in miliseconds of pw added ? this is great news !

you you are saying that (tpsacc-100)/10 = added pulsewidth in miliseconds? (negative value = decel)
that can be incorporated as calculated field into logviewer and be ...

Thanks Al, good info there ;)

hobieboy:
correct steady state fuel is not a really well defined value. if you tone the car to the very edge of misfires, you are then very dependednt on good AE, as you will get misfires if it's not fast/good engoug. BUT if you dont tune your car to the very edge of ...

thats right.
some other ecu's handle accelenrich in terms of engine cycles ~5 engine cycles. that basically means it's longer (in terms of ms) at low rpm's and really short at higher rpm's.

map lag factor 95 = nearly no lagging (100=no lagging at all, 10 = alot of lag).

You introduced a fuel ...

Thats great.

I basically want to see the relationship between PW, gve, ego reading, mapdot, tpsdot, mapdot, how fast is map to respond with respect to tpsdot....

definitely post few logs, i'll have a look

Hello Guys.

I'm strugling to get my AE tuned well. I would like you guys who have perfectly tuned accel enrich post a datalog of two with some different situations for AE, like low speed, low Ae amount, off idle AE, high speed very quick gear changes, etc...

I basically want to see how it should ...

aparently they update 2-3 times a second, which should be ok.

there are several different models on ebay right now, i'm looking at this 3 digit one (4 digit is 1 digit too much, pointless to waste dashboard real-estate), but it doesnt seem configurable, I'd have to build some circuit (resistor ...

definitely let me know how you progress...
I'm wanting to do someting similar, but to a less extent.

just like electronic boost controller, i want to find a on/off type solenoid and i'll use it to block wastegate signal until boost pressure is really close to the target boost pressure (that will ...

timing has important role at idle.

you want the timing at target idle rpm between 8 to 12 degrees normally. see what works for you best. you prefer more idle air, but less idle timing to maitain stable idle speed and make idle 'strong' - i.e. engine will not be dropping below idle revs (well it ...
