hey there guys have been a long time reader but first time posting i have recently had my 96 S2 R33 with RB25DET at the tuner after a bunch of new mods he was having an issue with the car hesitating for a second or 2 when the throttle is jabbed quickly.. making it feel quite un responsive and laggy ( throttle is fine otherwise, just has to be increased slowly.. its most noticable down low or when giving it a quick rev in neutral) he believed it to be a TPS issue so i got a new NISSAN TPS the same as what i had in the car. which surprisingly was a S1 TPS (obviously with a S1 Throttle body too, installed by previous owner) with the extra plug and fly lead hanging off it.... he managed to tune it ok but it still has the same issue - just to clarify ive got it plugged into the fly lead plug not the one on the bottom of the sensor.. i believe this is the signal plug so this is a two pronged question 1. other than the way the the TPS mechanicaly connects to the throttle body are the sensors both the same electronically? 0.5 - 5v DC? - if so it shouldnt matter that i have a S1 sensor on a S2 motor 2. when i tested it i seem to be getting 0.6v at closed throttle and 3v ish at WOT.. i believe its ment to be 0.5 - 5v from what ive read on SAU.. i have hesitated to adjust it as dont want to screw up the tune i have just had... but is this likely to cause the problem i am having.. or is it possible he has compensated for these incorrect voltage readings in the ECU (VIPEC) or something? any assistance would be greatly appreciated.. and ive been searching for a couple hours and couldnt find anything that answers this completely.. so sorry if this is a repeat post thanks caleb
