Ecr33 Rom Tuned Ecu Question

[chunky]

Hello all, this is my first post on this board. I'm in the US and own a 1997 S14 which I have just recently purchased an ECR33 clip for. The clip came with a ROM tuned ECU, and I was wondering if anyone on here has any idea whats been changed. Here are some pictures...

Thanks!

Top Secret are a big brand in the scene, the chip will probably be for japanese fuel tho, so to run it right 100ron.

yeah, top secret tuned... see how it goes and if you are not happy get a diffrent one, or a tuner to look at it

stick it on and go for a drive. listen out for pinging.

i have a remapped ecu in my 33. no speed limiter, no rich and retard, higher rev limiter, and runs a bit leaner than the stock ecu. at 11psi it sits at 12.0-1 at around 3500rpm then slowly drops to 11.5-1 at 7000.

it would be wise to put the car on a dyno after you have installed it to check the afr's.

get it on the dyno, and see what the air/fuel ratios are like. if you hear it ping, stop right away and retard the base timing a bit
