i have a JWt pop upgrade ecu 89-90 240sx mt sr20det.

370inj
89-90 ka24 maf
base timing 15btc 18mm zro2

this is useless to me and was given to me under false pretences. (told me i can use it on a de just need to be retuned, not the case. only det)

would like to trade for a calum de ecu.
or somthing i can use on my 240sx.

So the timing is the only thing changed?

its a jwt pop upgrade, theres a bit more then just timing..., also its chipped for a jwt eprom already, why pay 500 for you ecu to be jwt chipped, when you can just buy this and have jwt reprogram it for 100
