Pleasure no problem. I have a few more files from other cars, I'll post them also, hopefully helps some of us out to learn about map recognition etc....

These files are ebay DVD files. No good at all.

hi RPMfreak --

sorry but i disagree -- here is a screenshot of WINOLS showing the file contents, and it recognises the BOSCH ecu aswell.

These files i personally wrote onto the ECU myself in 2001 with Glallep prograsmmer using 29f400 PSOP EPROM

He probably means the remapping is not well done and could be much improved, just like the 406 HDi remaps we have seen hanging around that are just crap compared to a professional one.

I guess im not supposed to be telling you this - but this is an UPSOLUTE MAP -- and their maps are generally accepted as being a good map - so i seriously doubt it. The car made considerable power improvements and no issues at all -- i personally consider this map of a decent quality, purely based on the experience of driving the car.

If you want to hear my opinion these companies do not deserve 10% of the hype they get. Most of them, even renowed ones, just grab a standard computer made map and put it on your car.

For example there's been lots of interest about the Superchips remaps of the 406 2.2HDi in the relevant forum in the past. All are very enthusiastic! It's very easy to get carried away. Just to find out, when an expert analyzes the map, that it is utter crap, the torque curves make little sense, many times only 30% of the necessary maps are tweaked, the car gets smoky etc. etc.
A remap done by a real professional is on a different league.
Believe me, when I tried out ecuedit's car with the remap he did (he has the same car as mine, 406 2.2HDi), i could not believe my eyes!

So if RMPFreak tells you it can be done better, I trust his judgement by experience.

Thanks for the informaiton, i agree that tuning is an art, and many people can tune engines, some do it their way and other do it another way, if i take my tuning for example to ECUEDIT - he will have his opinion about it - and vice versa --

The same goes for everyone out there -- if the car shows gains that are 30% + improvements with no problems etc -- then im sorry to say the tuning is definately not crap. If the car's torque curve, power curve is all over the place, and the ECU throws errors, then for sure tuning or map changes are crap --

But this specific car ran EXTREMELY well -- i drove the car for two days, i put it on the dyno 4 times in the two days and all the power runs were above 30% improvement on pump fuel, smooth curves and no errors. Fuel consumption was also 100% and no other problems at all - in fact this car is still running today with that map on and has done over 250 000kms

I believe that even if someone else gets his hands on the file (which is freely available in the post - please go ahead) and makes changes to it, i cannot see many changes being made to this that will improve this file THAT MUCH -- showing a serious HP gain compared to where it is now (obviously without changing boost levels)

Tuning with stand alone ECU's is very simple - i have installed and tuned Haltech ECU's, UNIchips, SMT6, etc many times, including a Haltech Platinum Pro in my Skyline R33 which makes over 500KW - i tuned this myself alswell. The tuning process is so simple WHEN YOU HAVE THE TUNING MAP LAYOUT IN FRONT OF YOU -- e.g fuel vs load or ignition vs load etc -- Chip tuning through software that done show you these map outlines is where the difficulties come in -- also the additional maps that you would not normally find in lets say a HALTECH ECU software are also confusing and this could lead one astray....

At a specific boost which this MAP file has been tuned to 1.0bar with a 1.15bar overboost - the fueling and ignition has been setup to accomodate for our 93 octane fuel. If the tuning was so badly setup, the power and torque curves would shwow it, and the car would not run very well -- none of this is a problem.

Im interested to know why the comment is made that this file is crap -- can someone please explain why, as the facts remain clear, the car runs perfectly....

One thing i did notice inside the file was some sections were modified in an area where there is no values -- i assume that this is specifically to maintain the checksum in tact --- again this is an assumption, i might be wrong.

I agree that every tuner has his own way of thinking and tuning. The big difference between good file and not so good file is the time spent for testing and correctly adjusting the maps.

When you get your map pack you well see what am i talking about.

Until then, look at the spark advance maps(120E9 & 121B5). Use factor 0.75 to see the actual advance that the ECU uses.

Requested Load map at 150CA needs more work. Use factor 0.023438

Drivers Wish maps at 1625C & 16410 are left standard. Use factor 0.003052

Optimum torque at 16616 is bad. The torque in the middle of the map is raised but then at the end falls down bad. Address 16778 has 11 values that are X values in Optimum torque map. They are not checksum correction. Use factor 0.023438 and you will see the mistake that was made.

REV limiter is still set at 6800 rpm.

Lambda maps are still standard. You need to make adjustment to avoid lean mixtures.

What is the HP gain with this file? Did you make a dyno run with it?

Small hint - In some maps you need to lower the values to get more HP.
