I have decided to keep my 99 Si and instead swap in a 99 JDM B18C ITR motor compliments of Brian, b18c1_powered_si. The car is my daily driver, but will see some autocross and drag strips later this year.
The new motor will remain stock for at least 5-6 months while I save up for internal modifications and/ or turbo kit. The only things that will be added to it are my JDM 4-1 header and JUN cam gears to allow for some mild tuning.

Currently I have a Kenji re-progged P28 ECU w/ a Field's VTEC / Fuel controller.
Would it be adequate to keep the P28 and get a VAFC to replace the Field's?? Or should I go Hondata?? If Hondata, which level would suit me best??

Please take into account that cost is somewhat of an issue here. And the motor will remain stock internally for at least 5-6 months.

Anyone running either system, please comment on how it works for you.

 

 

Hondata would be your best bet later down the line, but with the mods you'll be having, you won't need it as much. I have seen gains from dyno tuning with hondata on a stock motor. I wouldn't use the same program on the p28 for the b18c. Think about it, 1.6 and 1.8. After getting Hondata, you can easily get your eeprom programmed to run the b18c. You can find the base s200 for about $250. Depends on how much you're willing to spend. But Hondata would be the best in the long run. That's why I chose it.

 

So a Hondata S200 would cost $250 base?? And I would need what else??
