Anyone chipped an 120 petrol engine

[rdkarthik]

If its 'chip', there are three possibilities that can work for you -

a) Throttle pedal modifiers - these dont increase power, but will enhance perceived response
b) CKP signal modifiers to advance timing - these work, and probably the best solution for J120
c) Ignition coil signal modifiers to advance timing - these typically dont work with the J120, as they have a feedback loop to the original ECU.

Ive remapped mine, adjusted timing, air-flow characteristics, target lambda, etc. Havent had the time to put it on the dyno, low end gains are evident, and with higher fuel efficiency too, full throttle gains probably ~5% or so. The part throttle gains are definitely worth it.

tune it. chip are a waste

I drive like an old fart but want a bit more pulling power fro the new caravan coming.
Maybe a set of headers and a better pipe + tune

Any power increase will put more strain. You are better to tune them, not chip.

Hey
Looking for some first hand info on outcome from chipping a 120 4L engine.
some of the claims on the websites in power gain seem excessive.
Any extra strain on drive line
cheers
