Renault 8 Gordini [MicroRusEFI]
So, new build / project started. It is not my car, but I must start it. ....
Engine is Alpine 1.4 liter with turbo ...
all wires and sensors must be produced and mounted.
I have no idea, what kind of trigger wheel will be used ..
..full seq or pair ...
"how to wire" ETB .. different pedal + different throttle body ...
not have fuel pump, 3+1 old injectors, one has broken connector ...
.. so too much fun ... on it ...

Re: Renault 8 Gordini
..mm.. some update ..

Re: Renault 8 Gordini
You may have some trouble with this trigger pattern and RUSEFI because of the abnormal long male tooth then the long gap. I work on a more modern Renault engine that has the same configuration in 60-2.
The Renix trigger decoder is probably untested on real engine. Expect to have to mill the long male teeth to go back to normal gap sequence.

Re: Renault 8 Gordini
SO ... tune and log are online ...
I have some problem with trigger ...
and it is not "mechanical" problem ...
(checked many times)
CAM is single tooth on HALL
CRANK is RENIX with original renault VR Sensor.
All signals looks good on scope.
VR polarity change has no affect ...
(..it has .. it can start or can't strat)
(no trigger readrings with bad polarity, the same as my other car)

Re: Renault 8 Gordini
What problem is that? How do you test and how do you know that you have a problem?

Re: Renault 8 Gordini
The unstandart teeth pattern causes first tooth to be too long on signal. Conséquences are not clear for me yet.

Re: Renault 8 Gordini
Maybe, the same as 60/2 vs. VW60/2 ...
as we discussed before ..
it is the same "hardware" wheel .. but readings with HALL vs. VR is different

Re: Renault 8 Gordini
I have a problem with ETB and I need help ...
It is RENAULT ETB (see pic) and they "default" position is aprox. 5% opened
without power.
It can be fully closed "by hand" or by electric motor inside.
ETB Auto Calibrate can reach WOT and full closed state,
calibrate analog inputs values,
..but when MRE stop the power ETB's motor..
butterfly take it's "default" position -- 5% opened and I'm got an TPS ERROR message
(accel pedal not work at / after this moment)

Re: Renault 8 Gordini
Stock Renault ECU drive Idle with this ETB from 5% opened to 0% reversed polarity on motor wires
..and accelerate from 5% to 100% - normal polarity on motor wires
PPS 0-100% = TPS 5-100%

Re: Renault 8 Gordini
actual tune is here ...
https://rusefi.com/online/view.php?msq=1066
(I'm forgot write link)
Car is't at my workshop now, it's hard to test something at this moment.
We have short video on friend phone, I can upload it .. "somewhere" ..
I have one idea.
Can I calibrate TPS manualy from "default position" to WOT
and after that, have Idle control "from 0% TPS to -5%" ,, ??

The TPS error you see is a safety feature, intended to prevent the throttle from doing something unexpected, causing the car to crash (stuck throttle is very bad!).
Please make a normal log in TunerStudio (set communication data rate to maximum!) of TPS auto-calibrate, and moving the throttle open/closed with your finger.

it is drivable below 30% TPS with no problem, engine can rev 4500rpm or more ...
.. 1st 2nd 3rd gear was tested only ... but it has no sense ...
Can anybody check log files please ..??
(cause I have no idea what's wrong) ...
Thanks.
