When my car was tuned incorrectly, it was over fueling. Would stall when I went from Drive to Reverse, and revs would dip/stall when the accelerator was stabbed at idle. An air leak(s) can also cause these symptoms. Has it been running like these since the day you converted to NA?
With all of those things... your zed i would guess would have less than 100rwhp. To summerise some of the problems... Rich due det sensor TPS not set correctly - can cause rich stumbling.. Rich due o2`s Rich due NA ecu on TT injectors Low compression motor TT diff with high gear ratio The TT fuel pump might be an issue aswell. Dont know how it would go on the NA ecu.
It's quite possible that when you fix your code 34 (det sensor) that it could run ok and not stall on take off. I can only guess what a knock map designed for 10:1 compression would do on a motor with 8:1 compression, which may be lower than usual due to engine wear. It's highly likely it would bog down and stall.
...and larger injectors, k value in NA computer will be incorrect. ECU needs socketing, and tuning for lower compression with larger injectors.
You could change the injectors to n/a type. Also adding another 5-10degrees timing on the cas may have it running well. If you go this route there will be no need to worry about socketing etc. You definately need to either change the k value or injectors. Your lack of speed is most likely due to a serious lack of hp caused by extremely rich fueling and lack of timing advance due to code 34 aswell as the engines need for more advance to suit the lloss of compression. Lower compression will require the air/fuel mixture to be ignited earlier) because of the minimal cylinder heat available for effective ignition.
Yep, if you still have the TT injectors with the NA ECU you will be dumping heaps of fuel down the exhaust. Change them over.
where would i start lookingfor these injectors and what are the cost? and at about 130 its revved out. bout 6000rpm.
what gear is it revving out in? I'm not sure about autos, might overdrive (4th gear) playing up, though i'd think 3rd would rev higher than that. Try forum member Chrispy for the injectors, he's parting out 2 non-turbo motors so he may have some. Tell whoever did you TT to NA conversion that they're idiots
Yeah I got two full sets in good nick in rails for $150 a set. Next time just buy a NA car and sell it when who ever is driving it is off their P's.
yeah mate im a first year apprentice with all trades so im not getting much at the moment. but once i get the funds together ill give you a pm. thanks matt
