    Martin was really helpful and stayed in contact with me through out the process. Also shout out to the enjuku team namely Wesley for being really helpful and quick to respond. If you need a good base tune, these are the guys to get it from. Oh, and they offer a launch control system!

    Had it done on a previous 240 several years ago and doubted it, had it retuned on the dyno in person and graph was so close I know I wasted my money on the retune. Now I bought another 240 with greddy emanage and it sucks! will be sending my ecu that way hopefully whenever I get the extra money.

  5. s13 Blacktop n62 rom tune

    R.S. Enthalpy is amazing got a rom tune through them and got so much more power, throttle response, quicker turbo spool and it's super reliable.

    This tune is awesome! A friend of mine has a 240 with an almost identical setup and it makes noticiably less power. Also my tune has the 2-step launch control feature which takes the guess work out of getting off the line quickly.

    '90 240sx, Blacktop SR20, FMIC, full 3" S.S. exhaust

    GO RS!!

  7. Kouki ECU code: NA

    Posted by KR5kouki on NICO on the bee's knees, man. Jim Wolfe told me they dont rom-tune kouki sr20det ecu's, but Enjuku does!

    the ecu is great. flattened out my torque curve AND maintained my whp rating.
    fmic, 370cc injectors, 255lph pump, z32 filter, custom intake, recirc bov and GT28[ebay], full 2.5" exhaust @ 12psi my car put down 292.3rwhp and 280ft/lbs.
