I would say...that in my previous car, audi A4 110hp, with very slight tweaks in :

- Torque limiter
- Svbl
- Turbo request + turbo limit

... we could get interesting improvements. I think smoke map and driver´s wish map are about 5mg higher than torque limiter. It´s not too much, but it´s something.

To go up 1 level, other maps needed to be tuned. And in a different manner.

Hello,

Since writing this post I understand alot more what maps need tuning but unfamiliar with CR engines. I have been looking at and playing with VAG PD engine maps with good results but not on my Renault Laguna yet.

Hi zok can you list for which maps have which factor, offset and presion. Also what units is the airmass in on the smoke map. Also why is there two turbo and n75 maps, where is the selector to tell you which one is used? Cheers

A friend of mine (that works as a car mechanics teacher) had it plugged to one of his OBD tool, and could do actuator tests, read and delete all sorts of DTC's (A/C, ABS, ECU, etc), change idling speed etc, and code anything but injectors. :) After an injection failure, I replaced all injectors with Megane 1.9 dCi 74 kW injectors (bought them very cheap in UK), and nothing really changed, except the idling is smoother and engine start is quicker. No coding has been done.

The cause of this non-ability is probbably previous modding - every original ECU dump allowed injector coding, but not my "original" dump. I tried with DDS2000 which I bought this month.

I am on vacation in Savudria (Croatia) right now, so I have a very limited web access. I can not access the data needed for map definition in winols as it is on my home server. The unit for MAF is miligram of air per stroke.

In my dump, there are two N75 maps and two turbo boost maps - they are mirrored, so they should contain identical data.

Yes, I had some troubles on Friday, my Galletto interface bricked during flashing (or maybe I messed the program up playing with non-SVBL values :mrgreen: :mrgreen: ), so the quickest way to get the car on the road again was to buy an used ECU and to flash it with my friend's MPPS interface. We did that (it cost me 40 eur :? ), so I have one spare ECU to learn. Now I have to buy a programmer for the EEPROM chip and get it running again. That means that I will also be able to learn how to do immo off with no fear of messing my car's ECU up. :thumbup:

Also had other problems on the way to Croatia - HP pump's regulator's seals got broken, and me and my future wife were really lucky to get the car off the highway with the engine off - luckily we had 150+ km/h on the clock.. :clap: I replaced those seals (I had the new ones in the trunk :thumbup: :mrgreen: :mrgreen: ) so we continued our trip with no problem.

When we return home, there will be a new MPPS interface waitning for me. :thumbup:

Will report about future progress, and when I come home, I will post the factors, offsets etc, and hope they are correct.. :thumbup:

Can't you use the MPPS to recover the ecu so you don't have to remove eeprom?

I can't seem to find the smoke map in my file then the x axis for air wouldn't make sense if this were true. Also my turbo maps and N75 are different and not identical although only by a small degree of difference.

You should of said got loads of MPPS v12's in but nevernmind.

Your so unlucky hope your trip goes all well though :thumbup: No more breaking things Zok!

Excellent but your ECu is edc15c2 and mine c13 so I think there totally different.

I tried to connect to the old ECU on the bench with Galletto and MPPS - no communication at all. :)

Yes, software is completely different. :angel:

In my case, both turbo and N75 maps are the same. If you notice a small difference between them, they're most probbably related to atmospheric pressure. And different fuel maps are most probbably related to different intake air/engine coolant temperatures.

...or different fuel temperatures. :)

Ah, your smoke map is probbably 79710, dimensions 16*16.

Renault's dump doesn't always contain axis definitions, but when it does, they're always BEFORE the map location.

My rail pressure map is without axes, but smoke map is with them..

Hi friend thanks for the replies :) I will take a quick look at that location. I looked in 16 bit mode and in decimal view and thought it must be around that point but could not make out any axis's. If i cannot make out the axis then how do i know the mg/stroke of air to work out my AFR that I want to allow? I can find the RPM Y axis at 79914 i think but this after map but were is x?

I would say selectors are coolant based rather than atmospheric or fuel temp but thats just me heehee.

I will post my mappack soon so some others can use it maybe to help them.

for RPM definitions try using ECM Titanium.. :mrgreen: But for mg/str axis, there is no way to define it accurately if your hexdump doesn't contain axes for the map... ECM titanium converts this axis to "0-100% load"... :thumbdown:
