guye_d Posted August 14, 2009 Share Posted August 14, 2009 Guys, Posted a thread before; having issues after my single install. My car is a 6spd VVTI TT .... now tih a T61 installed Got the single install completed, had a few startup issues, but finally got it to work with the emanage compensating for the 650cc injectors installed. Was having issues revving beyond 2k, so took off the emanage and reverted to the 440cc to determine if all was fine with the car. and therefore I would be able to look towards the emanage for my issues. Problem is, with the 440cc in the car is stuggling to idle; its apparent that the car is trying to learn, but dies after 30 seconds or so. also between idle and 3 k rpm, the car finds it difficult to rev, however, from 3-4k it revs just fine. This is all with the 440cc injectors installed. First Question is, should the car idle and rev fine with the single installed and 440cc injectors in?

guye_d Posted August 14, 2009 Author Share Posted August 14, 2009 We also pulled the engine to do lil things like change seals and gaskets, oil pump etc. Was told that it may be the TPS that needs re-calibrating. Any thoughts on this? Quote Link to comment Share on other sites More sharing options...
Scott Posted August 14, 2009 Share Posted August 14, 2009 As far as i know the car should idle just fine. Can't be much more help though bud. Quote Link to comment Share on other sites More sharing options...
Hermit Posted August 14, 2009 Share Posted August 14, 2009 I'm not sure if the vvti throttle sensor is the same, but the early one has a switch for when the throttle is closed. That's adjusted by rotating the TPS and checking with a multimeter that it's switching when the throttle is almost closed. So yes that could affect idle, if the switch isn't closing the idle rpm would probably be low. Don't know about the rest, I don't think the revving problem could be explained by the TPS Quote Link to comment Share on other sites More sharing options...
dude Posted August 14, 2009 Share Posted August 14, 2009 The only VVTI's that are single and run properly I know of are running F Con Pro's. Quote Link to comment Share on other sites More sharing options...
Miguel Posted August 14, 2009 Share Posted August 14, 2009 This isn't meant to sound condescending, but did you put the MAF back when you slapped the 440's back in? With the 440's and the MAF in place( emanage out of the loop) it should start and run like normal. Quote Link to comment Share on other sites More sharing options...
guye_d Posted August 14, 2009 Author Share Posted August 14, 2009 Thanks Scott Hermit, will check and post findings here Dude, Keep on hearing that the emanage won't work; bought it cheap off a mate so decided to give it a shot Miguel, not taken anyway mate, its the smallest things we sometimes forget; but yeah, the MAF is on.

Any thoughts on this? Only if you have disturbed the TPS. If they remain in the same position as they did before you pulled the lump, then they should be fine. There is a procedure for the vvti TPS in the WS Manual floating about somewhere. Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 14, 2009 Share Posted August 14, 2009 The only VVTI's that are single and run properly I know of are running F Con Pro's. Alex's one ran OK with an EMU in it Quote Link to comment Share on other sites More sharing options...
Jake Posted August 14, 2009 Share Posted August 14, 2009 The only VVTI's that are single and run properly I know of are running F Con Pro's. Mine ran great with a Motec M600. The current owner has got it running even better with a Solaris stand-alone. Quote Link to comment Share on other sites More sharing options...
Hoppy Posted August 14, 2009 Share Posted August 14, 2009 Don't know if this helps?? but my non VVTI Supra currently still has 440cc injectors and a stock ECU fitted.I've recently fitted a HKS T04Z single and it still idle's and revs perfect.

Runs like a bagoshite on boost though I assume Quote Link to comment Share on other sites More sharing options...
Hoppy Posted August 15, 2009 Share Posted August 15, 2009 Not using the car at the mo.It runs ok though under 4000 rpm.It hit's the factory boost cut soon after that.So i've decided not to use it untill it's all sorted, as i would be gutted if i got carried away with the throttle and ended up with cracked pistons or worse. There's a fuel system upgrade on the way shortly.Just fitted a HKS DLI and bought a AEM EMS + 3.5 bar map sensor to match. Can't wait to get this lot fitted and mapped Quote Link to comment Share on other sites More sharing options...

You're a 'braver' man than I... not using it is a good idea, hopefully it's still OK. Quote Link to comment Share on other sites More sharing options...
guye_d Posted August 17, 2009 Author Share Posted August 17, 2009 What readings should I be getting from the TPS? 0v off throttle and 5v full throttle? Quote Link to comment Share on other sites More sharing options...
guye_d Posted August 20, 2009 Author Share Posted August 20, 2009 A long shot .... but could this be my problem? Even if, I would still be interested in where on the intake it should be hooked up. Before or after the MAF. Thanks Quote Link to comment Share on other sites More sharing options...
guye_d Posted August 23, 2009 Author Share Posted August 23, 2009 update: Issue sorted; problem was the MAF was on 4" intake rather than stock 3" Quote Link to comment Share on other sites More sharing options...
Miguel Posted August 23, 2009 Share Posted August 23, 2009 Simples. Glad you got it sorted Quote Link to comment Share on other sites More sharing options...
