How Often Is Tuning Required?

[dougie]

hey all, alot of GTRs of have looked at on carsales etc have aftermarket ecu, apexi fc..

how often is a car required to be on dyno for tuning? i just want a nice daily driver GTR not a race car, and dont want to be getting tunes after every drive lol.

Every day bro, usually at 7am is the best because it's nice and cool and you might be able to slip the tuner cash before the boss comes in so it will be cheaper.

No but in all seriousness, if you don't plan on modifying the car then I would generally say.. Never, for example I have an R34 GTT which was stock for about a year.. Then I upgraded the ecu to an Apexi PFC, intercooler, coilpacks,zorst, upped the stock boost, this required a tune which I have now been driving on for about 3 months.

Basically I would only expect to need another tune if;

A - Something went wrong

B - I decided to upgrade something else (injectors, bigger turbo etc)

C - I decided that the first tune was pussy and I could of stressed the engine another 10hp (which I wouldn't do as I like my safe tune)

Hope this helps, I suppose the other thing to note is if you buy a car which already has an aftermarket ecu then the only thing you would need to question is who tuned it and how good was the tune, and also has anything happened between the last tune and you buying the car.

Cheers,

Once a car is tuned correctly, than that is it.

It is only when you change something major that you will need a retune.

Yup,

Even when major services are done (according to Nissan) at 40,000 80,000, 100,000 140,000 180,000 200,000 you don't need a retune unless you've done a performance upgrade.

Even changing plugs or coilpacks does not mean that a retune needs to be done.

Cars aren't pianos!

Tuning on most electronic fuel injection cars means altering ECU maps. Gone are the days where normal servicing was termed a "tune up".

thanks guys, i wasn't sure, i used to work near RX engineering and the same cars would be back on the dyno every couple of weeks, i wasn't to keen to be doin that. glad its not the case.

Power hungry doods with too much money.
