Do not keep your fuel in tank for too long

 

interesting...the 89980000 is a ix ralliart rom. So rolly has a modified gt ralliart ecu in his gsr. No wonder the car knocked so much. One thing that was strange about this rom was the timing. I'd never experienced a rom that would advance timing so much regardless of the ignition map. The ecu would still run timing beyond that of your map, if u decresed the map of would follow suit but not by much...it was like the ecu had a mindbof its own when it came to timing. Either that or there are ignition addressees yet to be discovered.

 

do you still have the address for the 2byte load for this rom? I'm running this the ralliart ECU as well and i'm having difficulty finding the address for the 2 byte load...

 

MUT41 > 0x840B (1-byte)
MUT 00 = 6B12(2byte load)
MUT 01 = 6B13(2 byte load)

 

thanks! its a great help

 

Usually you will see that the timing map is not correlated with your timing logs.
The ECU will add timing all the time.
He will not follow the timing set into the map.
I have also 48 timing degree (0-100 load area).
Like this you can face very often knock.
The ECU is tuned by ralliart for 100 octane gas.
This Ral ECU is different than OEM ECU (unit).
Still don`t know if this RAL ECU is suitable for a car with some mods other than RALLIART AIR BOX and PIPING.

 

So far i havent met problems with the timing. i set all 3 high octane timing maps to the same thing. But i do agree the Ralliart ECU is more troublesome then the rest. I'm running FP Red with no cams yet.

I face knocks on low boost and had to reduce the timing. also the AFR is really strange. The numbers are not smooth like other maps. had to adjust them to smoothen everything out.
