I am currently seeing myself as fulfilling your prophetical someone else, and perhaps also the right person. You're coming along for the ride, btw.

I feel like we're getting a bit OT from the topic of the thread. Perhaps we should have a moderator clean this up and split the two?
I just need someone to understand the assembly language to make everything come to fruition. All I need to know is what memory addresses to edit, with what, or what formula to apply to the values for display purposes. Also figuring out the other side of the map scales is a high priority, but can always be figured out on the engine simulator. If I ever acquire an Ostrich/Demon I plan to add RTP support, for now I have an equivalent work around, to fill that void. Also in regards to datalogging these ecu's should be possible as a cn2 connector exists, although the rom code to do so is missing in for the board series. Most likely either the p13 code would have to have modified to work, or adapting the same code used with the civic ecu's.

So yeah... Those are just some of the things ahead.

Thats about the closest you get to finding information about the 66911 processor. That file attached is for a 6691 DRAM Interface Integrated Circuit. The missing datasheet is for a 16-Bit Microcontroller... it should look similiar to http://html.alldatasheet.com/html-pd.../MSM66201.html

I got a pt3 (with the LED)
another pt3 with out the led eyelet
an OBD1 AUTOMATIC ECU FROM AN INTEGRA
and a spare P12

would any of these help the project?

Haven't had a chance to really continue the project, been really busy settling in here in California, I still do not have my desktop setup. When I get a chance, I plan to finish a few items, and then release a free developer edition so others can use the tool to look at the factory programming. Only feature that will be disabled/removed from code would be the save routine (which is currently unfinished). For each view mode, the save routine has to convert the view back to hex, and the current working memory updated in the proper locations.

Question

Question,

I was wondering if you will be selling Chipped ECUs with a basemap ?

I have a stock F22A1 5-Speed with a LSD H22A Transmssion(i had to take out my Tuned H22A) and the lose of punch when i hit the gas is killing me.

Not sure if this helps at all but a few of the late model dodges I've tuned recently have all used something similar to a MAF transfer function but they don't have a MAF sensor. The MAF values are inferred from the MAP sensor and the IAT sensor. I'm guessing the "MAF" table you found works similarly. Also, some GM's I've also tinkered with have 2 MAF curves. One for High MAF values and one for Low MAF values.

Edit:
I just checked out the pt-tuner wiki and on second thought the MAF tables you found are probably EGR tables. They look exactly like what I would expect them to.

Unfortunately I do not, and do not plan on selling chipped ECUs. If anything I might offer a service to chip/convert PT3's to PT6's, or Automatic to Manual in the future. I can and will burn any 'basemap' or .bin/rom that is submitted to me, regardless of what ECU it is intentioned for.

That is useful to know, and shouldn't be that hard to check when on a simulator.

Antoine, wtf are you doing with Dodges?


Every time I see this thread resurface, my first instinct is to open it and say "you can't tune a PT3/PT6!"... but now you can.

You know, I don't really like them either but if you want a flat torque curve that's still over 400 WTQ...look for a dodge. It's like the one good thing I can say about them lol.

It has been almost 3 years since I first started working on this project and have learned a lot. Unfortunately having a son who is almost 2 years old now, working full time, and moving cross-country, amongst other things have not left me much time to work on this software anymore. Since I first started writing this software, I've worked on several other coding projects, experimenting and learning different technologies, and have 'borrowed' code I have already written from one project to another, this software being no exception. As such I have started undertaking another major coding project (cryptco dot net), that I hope will be a highly lucrative venture. As such, with Fax4Free already being published, it bothered me that I haven't published what I've accomplished in regards to this project.

As such I have officially compiled the most recent edited version of my software, and it is now available for download on my site. This release is version Alpha 0.1.0.0 which unfortunately I never finished the save routine, so it is only useful as a viewer at this time, that can apply formula on the information displayed. I hope it helps someone with uncovering more information about these ecu's. Program is hard limited to reading 32KB files. Also the Version B when opening a file has a glitch on displaying the ignition maps, and will be addressed with a subsequent update over the weekend.

If you want to save files, I recommend copying the view data to your clipboard and saving it through a 3rd part hex editor at this time.

Also since this is new software, and is NOT open source, most antivirus and even web browsers (like IE) will flag the download, as such feel free to run it in a sandbox if you don't trust the download.

As an update, Version Alpha 0.1.0.1 is now available for download.

Changelog - Corrected Type B Ignition Map Start/End Locations to display properly, since they are using the 'reverse loader', it needed some small corrections.

Any chance you have the memory ranges mapped? I'm starting research on reading data from the CN2 port and displaying it live.

Sorry took so long to get back to you on this. I nor have my associates been able to get data logging to work with these ECU's yet, so I don't have that information available. I would recommend maybe looking at the reference material available for the other ECU's that are similar.

Holy thread revival batman! Can't believe it's been 5 years since I posted here. Upon digging through some files I deeply archived on one of my hard drives, I found a backup copy I made of PT-Tuner & the Wiki. As I am one who likes a challenge, wondered what data was left (as I've gotten several requests for information over the years), and if I could some-how revive the site. After several hours, and fighting hosting restrictions such file size limits and the likes, managed to successfully restore (an older version than I'd have liked) copy of the site. I've re-uploaded most of the assets (images) I still have (as Photobucket turned to garbage). Also went through some of the code and cleaned-up / corrected some issues with "Type B" maps. I also have re-published all the dumped BIN files for the F22A I collected on this project, so if anyone wants go BIN diving with the software, and potentially further the development of these ECU's, you can.

The new location of the (ZettaHost provided) site is: pttuner(dot)scienceontheweb(dot)net/wiki/

Given the unstable nature of free hosting, I cannot guarantee how long this site will remain up, so as they say "get it while it's hot".

I still have that PT4 I borrowed from Lindiz that I told you I would send you. How many years ago was that now?

And I'm even in Houston! You had to leave before my lazy ass could make the exchange!
