Hi. I just recently purchased a datalogger and have been working on tuning my car. Problem is for some reason my TPS reading will not go above 73.7%. Somehow this is just enough to throw the car in open loop mode but Im thinking this may be hurting me especially in spool times. I have removed the TB and cleaned it off pretty well but no change. Tightened the throttle cable and no difference. The TB opens fully when pedal is depressed and nothing is on my floor but still no go on anything. I did note on one log recently I got a 78% TPS but thats as high as its gotten. Totally confused??? If anything all the work I have done so far has made the car more responsive but I still cannot break the 73.7 barrier. Any ideas?

Is it possible it is just the TPS itself or is that possible considering I did ONCE go above? The one time of inconsistency is whats got me real stumped. And would only a 73.7% even send it into OL or is that a hint to the problem? Thanks
