ok lads i will try and fill you in with .....done so far with no results..?
but this has me stuffed..?
94 jzs147 aristo..still running true twins, owned 5 years + with NO problems till now.
running "mines" ecu, super R s/s system, hks front/dump pipe, first cat gone, gutted rear cat. fitted recently ::: new 02 sensor / VSV sensor / I.A.C.V / map sensor .plugs.
coil packs . A/M fuel pump .
probably other stuff as well , just cannot remember right now....?
on the dyno :::: 329 H/P to the rear wheels. she will not idle well, (was perfect! )on the road, you give it "slight" throttle and ok. give it a tab to much, and it shudders/hesitates, dont know what to do (so to speak ) now if you mash the peddle to the floor, or give it say 3/4 peddle push the car seems to jump over this "flat spot" and "GO !" will rev to 7500 rpm all day long, no missing or anything at all...?
i really believe i have a "sensor" problem....somewhere..? cannot be attached to the second turbo at all (at this stage its all go ! ) it is this ( big flat spot "nothingness" on easy throttle ) its like the first turbo does not know it should be spooling up..?
this is doing my head in..? the dyno tune bloke could NOT find anything wrong ? although the dyno did pick up the flat spot on the first turbo, no fault codes.....no vacuum leaks. i am going to change the "throttle position sensor " just in case..?
any help in regard to this problem would be very grateful, as i am at a loss .
all the best.............muppet :icon_surp
