Cant read Katech E67 PCM

[Sweet35th]

Working on a TA2 Katech built race car. 6.2L, non drive by wire, currently speed density, no O2s....Runs like crap. Try linking to it as an E67 PCM and it wont connect. V8 autodetect wont detect it either.....Is this PCM possibly totally blocked from aftermarket modification?

If that bad boy has a cable throttle, sounds like a COPO setup. If so, there is a good chance the E67 will be running MEFI 5 (or 5A) programming.

[efiharness]

Yes, The copo uses an E67 with mefi os. look @ a program called mefiburn to tune it. Steve

[Highlander]

why not go to a stock E67?

[efiharness]

the oe E67 is not as flexable as the mefi version (24x, 58x, dist, man or elect throttle, move vvt cams in both directions, etc). Steve

[Highlander]

That is interesting... I am guessing this is what MAST motorsports uses... I'll have to check....

[efiharness]

Mefiburn is what most people use to read and program these. You can read the data stream with J1939.

Thing is... I have a customer that has a 502CID with a "marine efi" ecu made from mast.. there are certain RPM limiters which he is NOT allowed to change and such... his program is rather limited on what he can change or do...

It would be interesting if one were to have access to all the parameters needed.... Not that it's really affecting it's performance (9.4@151 is plenty fast), but... there are a couple of things to be done with that car....

Thanks... very enlightening.

[efiharness]

You can change any of the settings with the software. Steve

Did not know that, no wonder I've never been able to talk to them.

[efiharness]

J1939 is most common on medium duty trucks (think top kick or Kodiak ), so snap on, Rinda, and others will read the stream. Steve

Feature enhancement? :D


J/K! Perhaps whenever the FS V3 is released you could include more protocol support, but unless the V2 can do it now I dont see a huge incentive to upgrade it.

[GMPX]

V2 can do it, problem is all the messages etc are unique to that CAN mode, it would mean another comms core in the firmware, a big job for one ECM.

Ah gotcha, that makes sense. Would only make sense if it would work for another ECM type or 2 and the plan was to support them all. I know dev hours arent cheap!

[04colyZQ8]

anyone have a MEFI 5a bin file? I am looking for one with 24x. Yes I know I cant flash it with efi, I just want to look at it.

[efiharness]

What do you need, I have 4,6, 8 cyl,man or elect t/b, 24x 58x, dist. mefiburn will write to these.Steve
