Who tuned it for you and how much was that? How much will it cost to tune next time you add mods?

Hondata stage 4: $845

EEPROM programmer: $270

OBDI ECU: $250

Socketing: $50

Chips: $10

Downtime while buying ECU from some kook on thepartstrader, then shipping it to be socketed, then installing it and tuning it: Couple weeks.

OR

AEM EMS: $1200

I can program on the fly without additional hardware, datalog, use wideband O2 sensors without any additional hardware, log additional sensors (try getting a Hondata to log a few accelerometers), never have to touch another chip, and I'm not limited by the godawful speed of a PROM. It plugs into my stock harness and I don't need an additional ECU.

Plus I'm using individual throttle bodies and therefore running my fuel maps off of throttle position, not a MAP sensor. Another option not supported by Hondata.
