spoiler: stupid question incoming!
why don't you add a 12V voltage regulator on the injector high-side?

(edit @ - I assume the idea is to eliminate the variable injector lag? Editing since do not want clatter the "Alternator control - PID implementation" topic)

Can I use two BAT41 instead of the double schottky?
Vbr and If seems about right.

After setting up the ecu, tuning it to the max with autotune, dyno, whatsoever, everything is just fine and good to go. now you are driving your car, lets say for about two weeks, around. in this time there is stuff which could affect some values, causing the tables to get slightly off. pid-implemen...

There are many approaches for many reasons. I don't think STFT and LTFT would be table tune-able. These are self learned, and I would expect they would be just a variable which is added to the fuel pulse equation. a basic only readable LTFT would be nice which the stm does by itself. such as this: ...

hi,
are you running the 200mm clutch?
you could try the flywheel from a polo mpi with 60/2.
just depends if it fits on the crank shaft and the clutch.

how old is your skoda exactly? and what model is it? felicia?

so we actually need two new trim tables in the ecu? one short term trim table and one long term trim table?! -- Once a second, if the variable is above something like 1% or 2%, then the Short Term Fuel Trim (STFT) variable is increased by 1%. Or if negative, then decreased by 1%. The goal of STFT is...

okay. thank you.

thanks. didn't read that thread properly.. .

edit: just ordered some VNP14NV04-E.

the bosch EV6 injectors im using have a resistance from 12 to 15 ohms. therefore a max current i think about 1,2A at 14,5V max. so it should be fine if i add a flyback diode to the injector coil? -> tc4427 in dip package is rated to 1,5A btw: if i have to use the 14NV04... is there a need of a heats...

i'm finally working on my ecu build again.

am i right that i can use the tc4427 for the injectors switching ground on inverting mode in tunerstudio?

i would rather say there are other issues now.

need to design a new vr-sensor bracket...
i'll probably integrate it in the torque support or something.

shot this thing on ebay by the way. ten bucks... freaking bargain if it works. Datasheet

My dad milled some pieces out of the crank dampener pulley so I now have 60/2 trigger wheel.

got the red and orange led steady on the third time now after burning something into the stm via tunerstudio with the todays .ini and firmware loaded.
the only way back to the blinking blue is a full chip erase.

any ideas?

I'm sorry!!! the drawing is not accurate! it's 135 teeth on the crank.

just didn't want to draw that much.

would this work?

Hi there,

I can select 5 cylinders, but there is no 1-2-4-5-3 timing order?!

Look what i've found: IMG_9567.JPG IMG_9568.JPG Audi 80 automatic ac connector which fits perfectly to the second gen. 7A stock engine wiring loom. :mrgreen: IMG_9575.JPG Was quite hard to get that connector of that old bord, but the heatgun did the trick. ordered parts: - LT1084-CP5 5V/5A low dropo...

no problem.

stm board is up and running, connected to tuner studio and so on.

now i should make a serious decision about the further electonics...

hallgebersignal = signal from the hall-sensor at the distributor
intern errechnetes Zylindersignal = internally calculated cylinder signal (calculated in the hitachi mpi, so I can't work with that)

i seriously really don't know yet. what i do know is that I'm going to build a completly new ecu housing with new mil-spec connectors like amphenol pt-series or so and a pretty much new wiring harness. rayfast 55m wires would be nice i guess. so space should not be that big of deal. apart from that,...

thank you for your help so far.

the 60/2 is an option the next time I tear that engine out of the bay again.
can i stick to the tripple sensor setup so far?


Btw. I got this like an hour ago.

hi there, your thoughts on that are totally right i guess. and after having a look at the diagram again i would suggest that the second crank sensor is not really needed when the cam sensor is in the correct position. these are the diagrams i found in the audi service manual. 1. cam hall-sensor (dis...

@kb1gtt: the crank signals are both VR. the camsensor on the distributor is a hall sensor.

@stefanst: moin! sorry, but I'm not going to post any pictures of the car.

etb is actually just a nice to have and not really needed.
it would make the whole cruise control thing theoretically a little bit easier i guess.

oohh... i have propably overlooked that there is no wbo controller yet... damn, my fault.

I just copied the post from the welcome thread to get the technical stuff started. :D I have a Audi Coupé Quattro 20V (7A engine / 5-cylinder) which comes standard with a Hitachi (2-connector) engine control unit and i already upgraded it to the later 4-connector Hitachi version. that gave me a bett...

thank you. yes, I have seen the wiki already. I just wanted that someone confirms my order. ;) the 7A engine (thats the engine code of the 5-cylinder 20V non turbo) in my coup is naturaly aspirated and manifold injected. i have some sort of plan to supercharge it, but that could take a while. tfsi e...

So i just ordered this thing and i hope it's the correct one:
STM32F407G-DISC1

just to get things right:

is this a replacement board for the STM32F4DISCOVERY with a bunch of more IO-pins?

or are you thinking of adding the chip directly to things like frankenso V0.5?
