Using Scanalyzer Protuner
 

I thought I would start a thread on Protune.

My first question is on the three fan settings, I currently have all three at 77 degrees Celsius, I am sure it's not optimal, but my fans come on at 170.

Any idea of what the first, second and third fan settings change?

:dunce::dunce::dunce::dunce:

Dump it and get the Cobb AP with Racetuner software instead

170 F is pretty early for the fans to come on. Car isn't even up to optimal operating temp yet.

My understanding is that the Protuner isn't at all user-friendly, and does not mask CELs. But it does have TONS more tables uncovered in the ECU than the Racetuner. If one is able to figure out those tables (they aren't labeled really) and utilize them in tuning, that is a great plus.

There are literally hundreds of tables in the ecu. I think at least 100 3d, 200 2d, and countless simple constants. Some look entirely vestigial, they're zeroed out or similar. Some look like the output of math functions -- sensor filters is my theory. Some seem to relate to limp mode.

I just think the vast majority aren't worth calibrating, and unless you connect to the Advanced User Debugger and write software to do map tracing, it will be extremely hard to figure out what they do.

AccessTuner Race is incomplete in many ways, but Cobb did do an excellent job of giving you access (get it?) to all the maps you really need to calibrate, and the some.

I admit, however, that I'd love to play with some of the unexposed maps, but that is just because I'm a geek.

Lots of exposed maps with no information on what they are, might as well be in hex code. I bought a copy and as far as I'm concerned its not even worth the shipping cost, let alone the ridiculous price I paid for it just to end up with zero support. Cobb could have done the same thing if they wanted to look like a pointless halfass job with a the potential to play with unknown maps that may result in boom ...

Unfortunately the Pro Tuner software was , in reality , at the development stage even though it was sold as a PNP product . Could have been excellent if more effort/$ had been put into it .

Rote8 , PM me if you need help with it .

Interesting thought, as I have one sitting here, but it has not been matched to my car and I do not have the Cobb software.

I really did not want to reinvent my tune on other software though..... :sad:

I suppose I may bite the bullet soon.

Just send the serial number of your AP to Cobb Tuning and they will send you a copy of the Accesstuner Race program

Assuming you can relate the specific maps to each other all you should need to do is transfer cell values from one to the other :dunno:

Sort of , but you still need to create a base map with appropriate loads , to transfer the values onto .

Cobb provides a Stock tune map to work from as did Hymee, though he had to provide one directly to you for your specific vehicle VIN/token as I vaguely recall. You can download the Stock maps by model year from the Cobb website. If both programs are based on the factory provided maps then I would expect them to have an equivalent map structure. If so (big IF), then it is simply a matter of comparing and changing cell values between equivalent maps. I have not verified this though since I gave up on Protuner long ago, do not have it installed on my current computer, nor otherwise tried to compare the two programs directly. I could be wrong and wouldn't be surprised if I was or wasn't whichever the case may be.

Does not seem like something too difficult to do. Based on model year, there might be a different number of columns/rows in some tables (though that may be ecu related and possibly be the same in Protuner as is in ATR), but it's nothing some interpolation can't solve. The main tables should have similar headings, except for maybe 'forward loop gain' aka 'Fuel VE.'

if I understood correctly, the discussion is about switching factory-map-based tuning programs on the same car so that would not be the case unless the structure of the supplied maps are actually different than the factory maps.

Again, in theory the software people have simply cracked the factory maps and provided you with a way to easily access and change the existing values within them.

My original Cobb beta tune was based on an early factory programming structure that changed between the time it was completed and when the Cobb AP was released for public sale. In this case it was mostly the fuel tuning maps. They were able to provide me some of the cell data that did not change, but I otherwise had to start over using the current maps. I still keep and use the beta map as my unmarried base tune as it's still accurate in all of the critical areas, but just not directly accessible for adjustment/testing. The point is the map structure can be significantly different and still function. So it just depends which map structure was used by each software provider at the time. I'm thinking they will have been the latest versions which haven't changed in a long time that I know of, but again have not compared them to verify.

/\I was referring to the changes needed to make an FI map . That is what Rote8 wants to do (I think).
Hymee actually supplied a base map for that ready to go . ATR only supplies NA suitable mapping and you have to make the necessary changes yourself.

Exactly, I do not know of a base FI map for the Cobb, the Hymee Protune starts with a base map and has settings for timing curves, fuel curves, injector sizes and FI specific settings that are plainly labeled, the Hymee software was intended for use in FI applications from it's first creation.

Done.

I will look through the race tuner software and see if I can feel confident that I can duplicate my tune without blowing an engine, I really want to use the tune I created so far.
Turning off CELs for the cat-less midpipe would be a time saver, as I need to clear the CEL after starting my car.

Gotcha. I wasn't aware you were FI. You can send me an email at

any one have the locations of the injector size parameters?
I found the latency maps but have never found the injector size parameter, so i can't really change my injectors to suit protuner.

/\ Discreet parameters 40 41 & 42

I only go up to 33 on discreet parameters.

what data type, scale and offset do they use?

/\under options click 'show unknowns' and they should be there . Very surprising that they are not there already - was yours a very early edition ?

I have got the show unknown's option ticked and there are only 33 discreet parameters.

maps 30 to 33 were "defined" as speed limits by hymee. the values in them don't make sense as parameter 30 is 162 (sounds about right for a .jp limiter), 31 is 223, 32 is 193 and parameter 33 is 360. not that my car has a speed limit; I haven't encountered one up to 210km/h.

could you go in to the calibration specifications and let me know what the data type, scale and offset the injector values use?
I also have the flash for a n3j6 pcm and it has only 28 discreet parameters, none of which are labled as injector size.

doh

this should help .....

neither of my maps for 2 different pcm versions, have those parameters after 33.

mine seems the same as yours up to parameter 33.

I might have to try hymee and see if he can help.
