Help to make a custom ECM driver

[awautosport]

Hello,

I have a Ecm 2001 driver fot a Mitsubishi Colt 1,6 16v without rpm limiter I know where i find the limiter, but I don't know how I set the adresslines in Ecm this is what a friend say on the forum

Your limiter is at location 4139h. There are two bytes, 02h, 26h (0226h = 550d). Divide 4750000 between that number (550) and your limiter should be 6800 RPMs real number, but 7000 with the variations of the analog tachometer.

i have added the driver whitout the RPM limiter

Ok can you help me to find the rigt limiter and set it in the driver ?

[tirlibibi]

You need to tell me the limiter offset and i think i'll be able to update the driver

I don't know what u mean with offset I am not realy good with tuning and adresslines. Normally the rpm limiter stands on 6800 RPMS

Is there anyone who can tell us what the offset is of the posted file?

Thanks

[tirlibibi]

The offset is the position in the file in hex!
On the driver you got Advance at 0x6b00

May be you can find it there:
ECM2001 6.3 (SW for ECU remapping. Include 9.700 drivers!)

Hello thanks for help, I have download this software and drivers, but the driver in the downloadpack dont show the rpm limiter, my posted drives is for ecm without rpm limiter and I hope I find anyone on this forum who can help me to updat my driver with RPM limiter.

Tirlibibi, take a look again. At 4139h offset, the value is 02h. I checked the file already. The limiter is there. Check the attached picture.

Hello,

Thanks again for helping me. I just have one more question, how do we change the driver so the Rpm limiter is in there?

Is there anyone who can tell me to set this adresslines in an ecm driver or howto set the rpm limiter on 8000?

[zilog357]

Here is the same original file you posted, except that it has a modified RPM limiter to 8000 RPMs for you to try (poor, poor engine).

As far as I know, there is no need of checksum correction on such file (guessing that it is for a 1990-1995 car).

Also, there was a typo in the previous information I provided, the base was not 4750000, but 3750000. So, the calculation is 3750000/(MSB,LSB) Bytes. Such number is always based on the crystal oscillator frequency.

Good luck

[awautosport]

3750000 that's something else that I thougt. I was making the driver and
filled in 475000 and when I loaded the driver I got a RPM limiter of 8600rpm.
But now I fill in 3750000 and I get 6800 rpm.
Thanks for your help and time.
