hello i am useing an apexi power fc sw20 airflow metter ecu to manage a 3sgte gen 2. and after haveing pluged in the ecu i have been geting the dash ecu error light up i have never had this fault with the stock ecu and am puzzled as to what it is. it does not bring up a fault code and when i had it pluged in to the computer at the shop i scene that the error was something called hte as it was iluminated in red. i cant find this pin on the ecu or any information in any manuals that i have and am wondoring if any one else has had this problem and might be able to shed some light or send me in the right direction to finding the fault???

also the tunner said that with the apexi it is only useing the afm for it's air temperature probe for air tempurature correction. he told me that the new ecu runs of the map sensor and it makes me wonder if i can remove the bulky afm and replace it with a manifold air temp probe/sensor of like a gen 3 or is there any other afm i can use for a better result i have heard of supra ppl useing an afm out of a lexus 400. with lexus being basicly toyota would this also work on 3sgte electrics?? or is there another afm i could use like a 300zx one maybe now that i have a tunable ecu. does any one know what voltage ranges these work in and maybe any modle numbers to look out for.

cheers
