I'm sure I can select full read on my galletto, and my MPPS
If your 1260 can talk to the Sirius then my friend we need to know what's in your 1260 as mine doesn't???
ah good to finally meet at some stage!Yes, only the one Scoff (thank the lord eh)
I can R/W the whole 512kb from the uproc (sirius 34) - but I don't think you ment that ?
The discussion here is really about what is happening in the 32kb flash. They wouldn't be this far along if they didn't already have the tool, software and ability to checksum.
I wish I had time and motivation for this kind of thing!
Then try it and report back! We need solids to go on!

Are you trying Sirius 32 or 34 ? 32 uses K-Line so maybe that is the problem.
my 1260 works perfectly on the s34. It won't talk to the s3000 though
I have to use an adaptor I made on my MPPS for the 32. It basically just shorts a couple of pins
Like wise I have downloaded my ecu map, and is what I've based my doc on. That was using the 1260 on the 182 s34.
Only 32kb read.
Right just been to the car with the laptop.
Using galletto 1260 I was able to download the 32kb file using the Sirius 34 option.
Using MPPS I was able to download the 32kb file.
No issues. To get the full EEPROM you need to use bootmode. But that's not needed for tuning.
I just need a wide band now

Sorry, there's a typo, 32 uses L-line (as well as K). With some tools you need to link L+K.
only just got my silver car back running after some issues, it is French after all, my red car got stolen so that didn't help either! I will have a retry with my 1260 and report backRight just been to the car with the laptop.

Sorry i just missedout this, Faboka, I'v just had a lot at work. I do not think there any change in the files for the 2,5 bar mapsensor.
At least not in the 172 ver.
but as "I have been told" it doosent work to edit the 182 to scale it to a 2 bar sensor. runs really jerkey. Makes me tink it might be
that the fuelmap is made by tps intead of mapsensor values. Either that or the mapsensor was faulty.
I made a guid at ecuconnections for bootmode read with galetto. Yes not the best soldering i have done, but it works nother the less.
//broken_down
By the way, the factors for ignition is from a megane 225 damos, and the way i see it i bet they use the same factors. does in deed look that way when i log atleast.

also managed to download a 32kb file using 1260, cheeky i know but has anyone knocked up an xdf for tuner pro on a 182 file? or is everyone using winols?

I use winols.

could never get on with win ols, will have to dig a copy out or get to work on building an xdf for tuner pro

That's what I'd be potentially looking at long term so I could keep all my creature comforts. I used to have a program for correcting checksums but it was for the vag stuff. Heavily supported but after searching next to no one plays with the renault stuff on a DIY basis....

what have people used for checksums out of interest or is it a feature in winols? i have a 1260 read of my clio trophy if anyone wants a copy to look at

ClioSport Club Member
afterlooking it looks like i will be restricted to my demo version of winols, 1 it costs loads to buy the full version and 2 they only sell to tuners. that sucks.... anyone help out?

is pin 28 defo the correct one for a sirius? ive not seen a pin out for the ecu yet. if i remember and it has been a while its pin 24 in an me7.5?

i never had to use a resistor on the me7 but some did. maybe it needs a resistor of some sort on the bootmode pin?

You'll need to defeat the immo before you can read the 32kb, so difficult on the bench. With the right tool you can put them in to boot mode and read/write the full 512kb through the OBD, immo or not. I've been doing a little bit of work with the embedded code recently. There are certain things you cannot fix in the 32kb (baro correction for one) and so it gets a bit more involved.

Alas there isn't a table for MAP sensor Faboka - you can edit RPM breaks but not MAP. This ECU was never designed for forced induction in any application as you know.
I've wrote some turbo files using DEKA / 225 injectors and a 2 bar map sensor. OBD reports 45kpa at atmo I can't do anything about that. Everything works very well apart from initial throttle opening during crank. That is skewed because the ECU thinks that we're 10's of thousands of feet ASL and so it opens it too far to compensate for thin air. I'd like to remove the baro calculation altogether from the embedded code, and that is my current mission. (The ECU uses the initial MAP reading pre-cranking and MAP reading at WOT to determine barometric pressure). I've been able to compensate for it to a large degree. I can set post-crank throttle effort in the 32kb so that other than the initial fire up (where it will jump to 3krpm for 0.5 sec if starting from hot) it will quickly return to idle and run fine thereafter. Having come this far I'm reluctant to say "that'll do". I want to be able to offer a good turbo map for the stock ECU with everything working exactly as it should.
I bought a test car to fudge about with, I've been driving it around (bog standard 172, just Megane injectors and a 2 bar sensor) so I can fine tune as I go. I've collected the turbo bits so I can turbo it but really the WOT tuning is very easy - making it idle, start properly from hot and cold and correcting the transients have been the difficult bits.

Sounds like your having good fun.
I know people did offer turbo maps for the stock ecu however how well they where setup I don't know.
I'll probably go down the external programmer route to read the full chip. Looks like the immo is effecting the on the bench read like me7.5's do. But that I can get in boost mode.

Love reading this, I'd love to be able to understand it. Sounds good though guys, better hurry up though I don't think there are many clios left that haven't been turbo'd!!
R5GTT, 2L turbo
I can send you some full reads if you want to look Faboka, but without decompiling there is not a lot to look at other than the 32kb portion which you can read already.
The turbo maps I've driven before have been a bit iffy, odd idle behaviour, VVT jumping in and out at cruise because (presumably) the table had not been updated to suit the larger map sensor.

Sounds like you are taking EXACTLY the correct approach to it scoff.
I assume you are only thinking of using the standard ECU for a low boost conversion? As the trouble is of course that if you wanted to do a high boost conversion you would then need a 3 bar map sensor not a 2, and the Atmo reading would be even more ridiculous, the ECU would think it was on the moon, lol.
I hope that if you do manage to really get it to work well that people recognise the difference between you doing it properly and the poor efforts done in the past, as the default answer we all give currently to if a turbo conversion can be done on the stock ECU is that no it cant as no one has bothered to do a decent enough job of the background work required to do it well and it sounds like you are putting a lot of effort in to change that.

There's one reason why I never did what your doing Chris and that's the copy shops! So much time to invest and once complete it will be copied. Yes you can change the keys for obd but that doesn't stop anyone with the ability to bench an ecu reading all the hard work!
So true, seen it happen loads of times in other makes.
Ok it needs slightly more skill than a chip copier on a c20let or YB ecu but even still it will happen if there is a market for a lot of people wanting them and if there isnt then no point doing it at all commercially speaking.
R5GTT, 2L turbo
Dead right Paul, I won't be releasing with stock software. I had these conversations right at the beginning - far too many hours sunk in to this already !
Low boost only Chip, you're just asking too much of the ECU to deal with anymore. I think in the past guys have used the 225 MAP sensor which is 2.5 bar, no ? I'm using a 2bar Delco, direct swap for the OE. That automatically means the baro fudge isn't a bad and it gives us a bit more resolution. The way the ECU calculates injector duty from the fuel maps is also a bit of a problem but not too difficult to get around. It might be possible to run 10psi or so safely but since we have no way of cutting power if it overboosts I need some headroom in the map to make it very safe if it does.
