GordR Posted May 30, 2016 Share Posted May 30, 2016 Evening Team,Have one of my starlets up and running this afternoon but struggling with spool.Its a forged motor, td04 kit with external wastegate, ultimate ecu and turbosmart manual boost controller, greIts very very slow at spooling, but does seem to boost ok when evenutally wakes up abeit with very poor control.Nothing until about 5k, and it totally flat below that. Also running quite poorly at lower revs, with eml light on. Now, I have had a look at the boost controller plumbing, which I think was incorrect, re plumbed with top port venting which is improved boost stability. But still very slow spool. Anything obvious I should be checking? Would an electronic controller help improve it? Quote Link to post Share on other sites
adzy Posted May 30, 2016 Share Posted May 30, 2016 Had trouble getting my ct9 to boost properly with a turbosmart manual controller. Spool was fine but boost was all over the place.Sounds like there is more to your issue tho Quote Link to post Share on other sites
richardc9052 Posted May 31, 2016 Share Posted May 31, 2016 One of the local lads has the exact same issue he is in a gt and he has tried swapping from standard turbo to hybrid... same problem Quote Link to post Share on other sites
GordR Posted May 31, 2016 Author Share Posted May 31, 2016 I think a decent controller would certainly help the stability of the boost, but unlikely to help the late spool. Quote Link to post Share on other sites
Socks Posted May 31, 2016 Share Posted May 31, 2016 Just remove the controller and run spring pressure. If thats your problem, your spool will return. Quote Link to post Share on other sites
funny onion Posted May 31, 2016 Share Posted May 31, 2016 Check that the wastegate on the turbo is closed properly. Since you're externally gated, if the penny washer isn't quite held shut it will give you a really late/sluggish spool. Had this on mine before, maybe worth a check...

GordR Posted May 31, 2016 Author Share Posted May 31, 2016 Good Shout Socks, Just remove the controller and run spring pressure. If thats your problem, your spool will return. That is something I had thought about, can you check by moving the external arm? Or does it ideally need the downpipe dropping off. Check that the wastegate on the turbo is closed properly.

funny onion Posted May 31, 2016 Share Posted May 31, 2016 Ideally you need the downpipe off. is the penny welded? or is it held shut by the arm? I made a solid bracket up for mine in the end. using the bonnet scoop bracket haha Quote Link to post Share on other sites
Ollieh17 Posted May 31, 2016 Share Posted May 31, 2016 Check airfilter, i had a problem with that recently. Didnt even cross my mind to check when i had no boost Quote Link to post Share on other sites
GordR Posted May 31, 2016 Author Share Posted May 31, 2016 Penny has been welded. Will drop the down pipe off. Worth a check Ollie, it has a hks mushroom filter which im never a fan of. Will try with no filter Quote Link to post Share on other sites
GordR Posted May 31, 2016 Author Share Posted May 31, 2016 Slight Update. Have done a diagnostic check.Showing code 12 and 52.Battery has been very flat, and is still in need of a good charge. Also traced the knock sensor wire back and found a break in the wire.Whether both of those codes are enough to make it as laggy as it is I dont know, I guess it would explain the rough running though?

funny onion Posted May 31, 2016 Share Posted May 31, 2016 12 is rpm/engine speed signal I think? but yeah knock sensor being effectively disconnected will make it run crap. I don't think lack of engine speed signal will make it run any different just puts the em light on I think Quote Link to post Share on other sites
RobSR Posted May 31, 2016 Share Posted May 31, 2016 (edited) Code 52 will make it run like a complete nail like suggested. 12 is no RPM signal, will also make it run like shit. Check your wiring around the distributor and ecu side etc. Edited May 31, 2016 by RobSR Quote Link to post Share on other sites
GordR Posted May 31, 2016 Author Share Posted May 31, 2016 Will get the knock sensor re connected and see how it runs. Any suggestions on best place to get shielded wire from? Quote Link to post Share on other sites

Check your wiring around the distributor and ecu side etc. May be totally wrong here but I think the ecu gets the speed signal from a pulse generator in the clocks where the speedo cable plugs in. Having to fit one to my EP70 clocks for the 4efte conversion :/ So if all else fails see if a buddy can lend you some clocks to check if it's your clocks or a break in the signal wire for the code 12 Quote Link to post Share on other sites
