Question about OMEX 600 ECU on Clio



  Renault Clio Williams
Hello,

I am setting an OMEX 600 ECU on Renault Clio Williams with Clio RS Flywheel and factory crank sensor.

I'm looking for the "Timing alignment" value for Ignition setup.


Who could help me please?

Regards.

Another question:

Who got Coolant/Air Temp sensor table for Renault factory sensors?

Thank you.

do you mean the timing pattern on the flywheel? as in how many teeth there are? or are you on about the spacing between the crank sensor and the flywheel?

you have to configure the renault sensors to work with the OMEX from memory (it has to be a dedicated sensor to the OMEX, ie you can't try and splice it so it feeds the OE ecu AND the OMEX, it has to be one or the other)

there's instructions on how to configure sensors in the pdf file on the omex website

I mean the timing pattern on the flywheel BTDC. I have 1.60 Teeth on my map file. Is it the right value for 60-2, 90° BTDC ?

I saw how to configure it in the manual but if someone has ever done it (heat water and quote coolant raw etc...) to avoid me wasting time.

i'm not an ecu guy unfortunatley but 60-2 is correct

i know that to setup the sensors you measure room temp (say 20degC) and enter that as a base figure, then put the sensor (connected to the ecu) into boiling water and enter 100degC and draw a line between the 2 values on the graph
 
This is for a 182 so not sure how comparable it is. If you PM me your email address I can send you the file.

Be VERY careful listening to this guy, he has a vague idea about mapping and you know the old adage of "a little bit of knowledge can be dangerous".

Speak to Andy @ GDI, he's an Omex approved dealer and mapper.

I have given him a screen dump of my settings as set up by Andy@GDI (LOL!). You dont need to do anything to the basic sensor config after the intial setup you r****d.

Get Andy to give you a copy of my file and check the config.

Also I am trying to help this guy out cant you get a sticky of your standard answer and post a link to it everytime someone asks a questions?

Get a copy of that and get a mod to sticky it. I will save people reading the same old s**t over and over and over you boring t**t!

All of the above is just a little light banter by the way :).

Please keep this ontopic, not a slanging match.

so marks post gets edited and the jesus's doesnt?

yeah that makes sense right enough.

if your looking for unbiased advice on the omex setup go to omex or contact one of their suppliers.

you wont get a straight answer on here withough someone throwing their handbag about.

*I THINK* the RSI is the same as willaims/16v which is vendix 30-1 X2 (or whatever is it!).

In which case your Omex wont read it (unless you use a distributer).

Best bet would be to use a megane 2.0 16v F7R flywheeel, or F4R flywheel, which is 62-1. the refernce angle for the ecu config is 90deg's.

I have F4R flywheel, the engine starts.
The only thing is that my map advance in not real because of the ignition timing alignment. Omex couldn't give me the good value for Renault car and I don't have strobe light to check it.

On OMEX ECU you have to put the 90° BTDC in "Teeth" and not in "degrees" like the other ECU.

The value in TIMING ALIGNMENT needs to be 1.7 teeth. In the SETUP/SENSORS/CRANKSENSOR menu CRANK RISING EDGE must be ON and FALLING EDGE must be off.

Thank you.

What about the cranksensor wiring?

Omex blue / red loom wire for A or B pin?

Regards.

I have set it to 1.70 teeth.

On idle it seems to be ok my main ignition map advance value is the same as "Spark total" (Basic idle options are off).

But when I load the engine at 30% TPS for example, "Spark total" is about -7° in spite of the value I have put in the main map ignition advance.

It looks like something in the map file does correction on the main ignition map but I don't know what.

Could someone send me a basic OMEX 600 v0.70 start-up file for Clio RS tb's?

Thanks.

It will likely run with the crank sensor wired either way round, but the "wrong" way round will limit early as the signal will be inverted.

Is it only reducing spark with load? sure theres no air/coolant temp correction going on??

there is no ignition air or coolant correction in the map - at all!
just looking into the rest of it.....
 
  Renault Clio Williams
I have found it! it was the Ign r****d RPM table.
Spark total is ok now

What about the high exhaust gas temperature?

the problem is the antilag is turned on... you have it set to 3000 rpm, so after 3000 rpm it massivly retards the ignition timing...hence you have 40degrees set timing and showing -7 spark total.

i will send you a megane map with all the settings and a sesnible igntion map to get you started... i must stress though this is only a start map with the correct settings.

you will still need to set

TPS when you upload

which injectors do you have?

Could you confirm my loom is good please?

Coil (Clio RS SAGEM/VALEO):

pin1: violet wire
pin2: yellow wire
pin3: +12v
pin4: nothing

Having the car in front of me, spark wire is plugged from right to left (1, 2, 3, 4; according to the coil number)

Injectors:

brown wire for left and right injectors
white wire for middle injectors

Crank sensor:

white cps wire to blue omex wire
blue cps wire to red omex wire



Regards.

oh... your ox sensor table is also out... 0 should read 1.03 straight line to 0.95 at 48 (or something pretty close to those values)
 
  GDI Demo 182, Rsi Spider
yes.... but its far better to map it on the rollers....

you must map with ox feedback set to 0 on the rollers...
