csa Posted December 15, 2006 Share Posted December 15, 2006 so...bought the car 1½ month ago, and just got i dynoed at 405hp and 500nm at the wheels, wich is not that impressive considering my setup: Boostlogic T67 kit Fuelkit with 1000cc's GReddy 3 row IC piggyback MAP ECU 3" downpipe HKS superdragger 1.3 bar controlled by a bleed valve I suspect that it could do with a remap as the hp curve is spiking quite a lot even though the boostpressure seems stabil. I'm not really interested in a larger turbo as I think the potential in this one should be sufficient for my needs, but what should be my next mod (apart from a remap) to clear 500rwhp? pics here: http://www.bilgalleri.dk/html/gal_visbil.asp?ID=73542 Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted December 15, 2006 Share Posted December 15, 2006 Do you have the dyno chart you can post up? Quote Link to comment Share on other sites More sharing options...
csa Posted December 15, 2006 Author Share Posted December 15, 2006 oh, and by the way, how do I see if my turbo is a DBB or not? Quote Link to comment Share on other sites More sharing options...
csa Posted December 15, 2006 Author Share Posted December 15, 2006 I will get it scanned during the weekend hopefully Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted December 15, 2006 Share Posted December 15, 2006 oh, and by the way, how do I see if my turbo is a DBB or not? do you have a close up of the turbo? Edit, just looked at a picture on your site. I can't see a water jacket, so no it's not DBB. Quote Link to comment Share on other sites More sharing options...
Wez Posted December 15, 2006 Share Posted December 15, 2006 1.3bar is a little low, should be able to run about 1.4 - 1.6 if setup correctly. Quote Link to comment Share on other sites More sharing options...
csa Posted December 15, 2006 Author Share Posted December 15, 2006 1.4-1.6...also on the MAP ECU? heard that it's having problems with fuelling when reacing more than 1.3 ? Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted December 15, 2006 Share Posted December 15, 2006 1.3bar is a little low, should be able to run about 1.4 - 1.6 if setup correctly. steady Wez he is on a stock timing map Quote Link to comment Share on other sites More sharing options...
Alex Posted December 15, 2006 Share Posted December 15, 2006 You should be able to clear 500RWHP at 1.3bar...so I'd say the map is wrong or the engine isn't healthy... What are your AFR's at 1.3bar with Wide Open Throttle 4000+ Rpms Quote Link to comment Share on other sites More sharing options...
Wez Posted December 15, 2006 Share Posted December 15, 2006 steady Wez he is on a stock timing map Ahh I see, does the MAP ECU not allow timing changes then? If not then could that be why the figure is low? Quote Link to comment Share on other sites More sharing options...

What are your AFR's at 1.3bar with Wide Open Throttle 4000+ Rpms I'm still a noob...what's "AFR's" ? Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted December 15, 2006 Share Posted December 15, 2006 Ahh I see, does the MAP ECU not allow timing changes then? If not then could that be why the figure is low? It can't Wez, but I would anticipate a lot of timing as the stock ign map is very aggressive. I suspect, it's either silly rich, it has a boost leak, or there is a more serious problem.

rob wild Posted December 15, 2006 Share Posted December 15, 2006 I'd did'nt think the ignition timing was a problem: http://www.mkivsupra.net/vbb/showthread.php?t=80054 post 13 I know that i'm running more HP than that with no adjustment to the ignition timing. Im not doubting you terry! could you explain why you would change the ignition timing? Intrested from my on cars point of view? Thanks Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted December 15, 2006 Share Posted December 15, 2006 The stock ignition map is very aggressive. I very much doubt any Stand alone cars here run as much advance. I never said it was a prolem, but it will limit the about of boost pressure you can run on pump fuel, whereas with a full stand alone you can back the timing off and run more boost ( I personally prefer less boost more timing on small single cars). In some instances a single car may need to pull a bit of Ign timing ( ask Ian C as he has tested T67 size turbo running a piggy back). That is where the MAP ECU falls down and the E-Manage can be a better prospect. HTH Edit just read Jarretts comments, but they are at odds with what myself and others have found here on UK fuel. maybe it's a JDM Vs US thing on the timing maps, maybe they have better fuel. When Jarrett says the timing map is fine up to 2 bar, I agree, but he is talking about race fuel, not our pump fuel. HTH.again Quote Link to comment Share on other sites More sharing options...

csa Posted December 15, 2006 Author Share Posted December 15, 2006 no a regular driving...it tends to drop a bit when giving it the go Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted December 15, 2006 Share Posted December 15, 2006 no a regular driving...it tends to drop a bit when giving it the go That will be the car going into closed loop. Thats normal if its around 14.7. What are the AFR on the AEM when on boost at Wide open throttle? Quote Link to comment Share on other sites More sharing options...
Alex Posted December 15, 2006 Share Posted December 15, 2006 AFR = Air to Fuel Ratio. You should be at about 11:1 at Full Boost over 4000 rpm. You should be at 14.7:1 when cruising/idling. Quote Link to comment Share on other sites More sharing options...
csa Posted December 15, 2006 Author Share Posted December 15, 2006 I will have to check that during the weekend! Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 15, 2006 Share Posted December 15, 2006 In my opinion you should invest in a proper standalone ECU and a decent mapping session, and see how it SHOULD run! Given the timing in the stock ecu is going to be miles out in many places this would be the best move, long term. Quote Link to comment Share on other sites More sharing options...
csa Posted December 17, 2006 Author Share Posted December 17, 2006 got a pic of the dyno here http://img375.imageshack.us/img375/6414/dsc00124cy8.jpg Quote Link to comment Share on other sites More sharing options...
Homer Posted December 17, 2006 Share Posted December 17, 2006 What an extremely odd dyno result. Something isn't right there! It dies at around 5400rpm - the bhp should continue rising smoothly until near max rpm. Either there's a fault or the map is screwed.

Alex Posted December 18, 2006 Share Posted December 18, 2006 It is indeed odd. Wheelspin, Boost Fluctuations and AFR fluctuations are all candidates. The wibble at 3800 is the usual lack of mapping round the sequential change over the stock ECU is trying to do. The wibble at 6000rpm is the really odd bit... Did you find out what AFR's you run?

csa Posted December 19, 2006 Author Share Posted December 19, 2006 finally got a reading of the AFR meter...showing approx 14,7 on idle/normal driving, but a wide open throttle it went all the way to the green side but only showing 3 dashes (---) guess thats off the scale? what does that mean?
