I have it from a good source that this person has done the same thing as AAAcomp, I will keep this one as a spare, that way if anyone needs it I will have it available.

Same as JWT with redline, speed limiter (lack thereof) and so on??

Hmmm, something tells me that there will be SOMETHING different about the JWT..

[GreenQ45a]

Does JWT just swap out the EEPROM?

[elwesso]

Yes....

[Q45tech]

JWT installs a eprom socket whereas the oem was soldered in.In Reality all one can change is WOT ignition advance [increase] and injector open time [reduction], tip in ignition retard amount and the rate it adds back in, speed limit, rev limit [hard and soft] .

No difference Wes, this is the same ecu I currently have in my car from AAAComp and it works perfect, no speed limiter and rev limiter moved to 7300-7400 or whatever it is, Gleen is still offering the ecus by the way, I will have him do my TCU next

So is the EEPROM* on that green daughter card?

Or is it surface mounted on the mainboard?

*EEPROM (electrically erasable programmable read-only memory)

Theirs (according to them) is a proprietary daughter board (card) that replaces the OE & accepts the eproms. I've had several apart & it has their name on it.
