Chipped Ecus ??? opinions

[gtlegacy]

Just looking at getting a chipped ecu in the future for my bd5 rsb 97

after opinions on different chips or complete swap over ecus

for example mines prova syms etc etc and what they actually changed and it they are really worth while

I have a chiped ECU.. I'm not 100% sure what the chip is exactly but I found that it makes a great deal of improvement. Acceleration was smoother and the car just went harder on boost.

They improve the air/fuel ratios, smooth out torque curve and some can increase boost. They can also take out the 180km/h speed cut, and can raise or remove the rev limiter. Each chip will be slightly different but essentially do the same thing.

Only down side I have found is that the standard clutch doesn't hold up very well with the increase in power. My clutch is still holding together......just...... but sometimes slips under load on boost in first turbo, especially in 2nd & 3rd.

Aftermarket swap in ECU's for your model car are rare as hens teeth, so I would say if you spot one grab it. It does everything that GT_Head said; remaps the timing to get more ignition advance, leans out the fuel in certain regions, remaps the boost and removes a few limiters.

Mines/prova/syms all seem to be similar products, I think you'd be happy with any of them. Be wary of the weaker EJ20R engine you've got though, I hear they don't like being pushed too far
