Check out this on a Mazda forum

Ok I saw this the other day and was wondering could we do something like this to our cars (04 Lancer Ralliart). It would be cool if we could. Give me your feedback please. There was also something about grounding your throttle body on the negative battery terminal. any thoughts on both of these mods would be great.
its called Advanced Ignition Timing Mod

Yup, been done, need to tune for it, though, and it's really not the proper way to deal with your timing, as it just makes one sweeping adjustment without accounting for load or RPM.

Hey Otter,
How would you go about tuning for this? Would the way in the forum work at all or would not be good to do? Also where is the crank sensor? Would I need a piggy back or something in order to tune for it? I know that there are not alot of companies working with our ECUs and all I have seen is the RRM piggy. I am also on a very tight budget at the present time and was wondering what else I could do like the grounding kit and what not for the cheap to gain some performance or improve something on my car. I could also if you want give you a detailed list of what i have done already. I have written it all down but don't have it with me at the moment. Off the top of my head let's see throttle body coolant bypass, throttle body spacer custom made, cold air intake- ram air throught hole cut out next to fog light, 2.5in. exhaust-test pipe no cat. w/ flowmaster 40 series, don't have header yet either, also have pcv bypass, egr delete, cut shifter down, and i think that is about it, oh yeah RRM rear strut tower brace, else you can tell me just let me know. I know your one of the higher ranked people on the forums so I figured while I got ya on here ask what i can. Well, Thanks for the help

Yes it is possible but no it won't work very well. There are some places on the map where Mitsubishi is very close to the minimum best timing. The other thing is that knock reaction in the ECU is just one calculated value and the timing is interpolated between a high octane and low octane timing maps (same deal with fuel). So as it detects knocking your entire knock advance will fall back and the open loop fuel strategy will end up much richer.

You should also never rely on the knock routine to reactively pull timing to avoid detonation. The stock ECU will eventually try to move back to the high octane timing/fuel maps by reducing the knock value so you end up detonating, the ECU compensates, then later by re-adding timing it detonates again. Not good for your engine.

so its best not to mess with then i guess. thankyou for your help man. That gave me a good insight into it and i guess i am not going to mess with it i don't think. I mean if I did do it could it really mess things up?
thanks for the help

I would have thought that if you did this by moving the crank position sensor, that it would work and that the ecu would learn this. I also always run 93 octane fuel and i heard that you would have to if you did this to your car. Any other thoughts on this would be great.

for cheap little things to do you could do a "Throttle Body Coolant Bypass" cot like 3 dollars to do it

[mazda8799]

done that and unplugged egr. what else you got
