Bump. Need to sell.

Here's what Mike Kojima says about the program (from http://www.se-r.net/car_info/engine_performance_tuning.html#ECU%E2%80%99s):

JWT’s ECU significantly improves transient throttle response making the car feel much more lively as well as providing more total advance at WOT. The JWT ECU also leans out the A/F ratio at WOT to an optimal 12.6:1 as the SR20 tends to run rich under these conditions. That’s a reason why the fuel pressure riser does not work too well on our cars.

The JWT ECU adds up to 8-10 hp is some parts of the power band and generally adds 3-5 hp on top. The ECU can take up to 0.3 off your quarter mile time. If you follow the same driving pattern with the JWT ECU, it has the potential for better fuel economy, as well. Premium fuel is required and 15 degrees of set timing is recommended.

For the 200SX, the JWT ECU is almost essential as this car is saddled with an annoying 109 mph speed limiter and a crappy 7100 rpm fuel cut. The ECU really adds to the driving pleasure of these cars.

If it only was a OBD II ECU....

Free bump for a good seller.

It is. All B14s are OBD II

Really??? I though they started using OBD II in 1998 :eek2: I learned something new :biggthump

So why not use it on a 1998 model??? Excuse my ignorance. :(

100% sure. 7250 rpm before, and now with the G20 ECU my redline is 7500 rpms :D

And it went up to 115 until it cutted. Here's the evidence on her first top speed run
