Upgrade Ecu.

[popinr33]

Hey i know skylines run rich on the factory tune. I heard this was for safety reasons. So does this mean that putting in an aftermarket ecu can potentially damage the engine even though it will be tuned better?

Just been wondering, any advise will be rad.

cheers.

The factory ECU doesn't run overly rich if you leave the car standard, but if you start to modify the car (exhaust, intake, turbo etc), then the stock ECU will over compensate, and overfuel. For minor mods you can just get an SAFC, which modifies the signals to the stock ECU, and helps control the fueling.

A well tuned aftermarket ECU will provide the right amount of fuel for the mods it has been tuned for, but if you change the mods it will require to be tuned again.

Hope that helps.

^^ what he said

tune = suit mods = more power

power = shortens engine life = more mods/rebuild = more power

repeats sets 1 and 2 until you've had enough or go broke

whether it damages the engine or not comes down to the tune and how lean much the tuner leaned on it

woops?

If you have a good tuner and take good care of your car (regular services and keep limiter bashes to a minimum) i dont see why it will shorten the life of the engine.

stock cars can die from mistreatment even with the "safe" factory tune
