Some useful info on how a free running timer is used and stuff.. Interresting how the resulting value always comes out correct , well...
Having grown up with a little bit of assembler on the c64 and amiga500,although on the c64 and in school it was'nt really assembler but machine code typed in by data statements, 68000assembler is really quite interresting too but as I remember, there were some pretty freakish god damn ways of...
Could'nt spot any difference no, but some other person might have better luck :-P (I measured the voltage out from the ecu to the vsv while revving the engine.. )
so if I understood the translated datasheet, address 0x0 to 0x2f becomes external through address/data? Does that mean that ALL...
I guess the really hard part is figuring out exactly how that logic works.. VHDL is cool.. I've been reading a book:"VHDL for dummies" .But simple l74-alike logic seems easy to implement in a vhdl. I did play around a little with quartus pro4, one could select four modes as I remember: C, vhdl...
if sin1 is changed in 7mgte ecu it seems like egr operation is still there. it was kind of a longshot anyway that it might be the same but I just had to try..
I'm going to play aound with it a bit more, ran out of time today, fixing some other stuff on the car, trying to get the cruise control...
True, true..
hmm time to start desoldering the cpu (with a pace sx-80 ;-) I don't trust hot air for that.. )
So what differences do we have left in ecu's? california ecu measures exhaust temp.. hmm anything else?
THANKS!!!
This is awesome, I was looking in my backup 7mgte m/t ecu and it seems SIN2 is connected to + via resistor R614 and R613 is missing and goes to gnd.. so it might be interresting to see what happens if R614 is removed and put in R613 (if SIN2 means the same thing in both ecu's)hopefully the code...
Did this thing a while back on a lunchbreak at work.
http://hem.bredband.net/nikwal/gauge.gif ,does'nt have to be as complicated as in my schematic though.. I use the same circuit for oil pressure..
How true.. My local tuner is going to freak out when they see my diy safc :-D hmm anyway, My 5cents is ,go with something that goes on the injectors if you're going for much power (as I'm not)..
Did you say that you couldnt se any diagnostic lamp blink? It sould blink.. try measuring it directly at the ecu then.. just hook up a small lamp there or something. I'm thinking fuel cut might be lower due to a fault condition..
Also, it cant be wrong to keep an eye on Vf signal, just to se...
Finished... does it look aaight?
installed it in the car today, sort of permanently, still a thick layer of snow outside though and got no winter tyres... buääh
2% memory left for goodies ;-)

[Edit] Making experimental MAP*RPM = flow conversion from mapsensor to...
I hate to say it but since other things seems ok, did you try with another ecu? I'm thinking that if one step is not stepping, if its moved to another position it might start to turn. mayne even have to measure resistance of the valve from within the ecu to rule out everything in the wireing...
http://dsl.mine.nu/nafc.htm Contains pretty much all info needed to build it, if you think a bit for yourself and look in the datasheets.. I'm in the process of making a circuitboard layout in eagle..
Just realized I made a video a while ago..

p= u2 /r , so if there is 5V (i'm not saying that it is just IF), in 10ohm it will be 2.5W
I=u/r , again IF 5V ,it'll be 0.5A, that seems like pretty high numbers for a sensor hehe..
Are you sure you dont mean 10k ?
Also found this...
If I remember correctly, thoose will fit the front brakes too only thing is when I stood there a month later, scraching my head thinking where the HELL did I put the bolts for the flywheels... so that was from a 4age, I always wondered where I got the extra bolts from..
