Badgaz Posted April 11, 2014 Author Share Posted April 11, 2014 to be honest its been a very long time since i checked it....i will check it that way....i was having trouble with my idle the other day and noticed that the map shows 20 but the actual logged timing was 15 degrees so i just set those first cells to 15 anyway. previously i had just set them to 20. i will definately check it before going on the dyno.

Badgaz Posted April 11, 2014 Author Share Posted April 11, 2014 so how do i shorten the ramp rate? Link to comment https://www.sau.com.au/forums/topic/441761-map-tweaking-questions/page/2/#findComment-7255765 Share on other sites More sharing options...
Dose Pipe Sutututu Posted April 11, 2014 Share Posted April 11, 2014 You want a long slow ramp rate, ask the dyno owner to do it. I'll post up my timing map later tonight for a comparison 1 Link to comment https://www.sau.com.au/forums/topic/441761-map-tweaking-questions/page/2/#findComment-7255897 Share on other sites More sharing options...
Don Dada Posted April 11, 2014 Share Posted April 11, 2014 no problem just trying to get maximum efficiency. can you not get detonation with too much fuel? conversly with too much ignition? seeing as this is at the high end of the rpm scale i tought perhap a degree more timing might help.....this is where my thinking was going on both.....might have to do what gtsboy suggests You can get det even though you throw alot of fuel in there, as with ign timing. Best bet is to get it on the dyno, set up your fuel and then play with timing, Add a couple of degrees at a time and see how it responds power wise and look at knk levels of course. When you reach the point where it makes no more power or very little for the changes made, back it off a few degrees for safety and yo should be good to go......Only way to know, as you wont feel these changes on the road. 1 Link to comment https://www.sau.com.au/forums/topic/441761-map-tweaking-questions/page/2/#findComment-7256258 Share on other sites More sharing options...
Badgaz Posted April 11, 2014 Author Share Posted April 11, 2014 thanks for all your advice guys i appreciate it. i just wish dyno's werent so costly to rent.... i'm doing my best to learn to tune on my own car. i'm tuning my wifes GTR next...however thats quite another kettle of fish the factory ECU she has was tuned by Torque performance, i'm going to tune up her powerfc the best i can and then dyno compare both ecu's....its my new hobby and i'm really enjoying it.

Dose Pipe Sutututu Posted April 12, 2014 Share Posted April 12, 2014 and here we go, just note I'm running 1.2 bar of boost, so it interpolates between 216/233kpa i.e. between 1.16 bar & 1.33 bar.. my theoretic max torque would be between 4000 4500 rpm, but saying that I haven't added much more timing after max torque as the car hasn't seen a dyno yet - waiting for the larger injectors (if I don't sell my car by then lol) These timing values are some what conservative as I roughly punched them in a few days before a track event at wakefield 1 Link to comment https://www.sau.com.au/forums/topic/441761-map-tweaking-questions/page/2/#findComment-7256453 Share on other sites More sharing options...

Dose Pipe Sutututu Posted April 12, 2014 Share Posted April 12, 2014 Externally gated hypergear SS2, I could run more timing but haven't put her on thr dyno yet. I've Maxed out my stock injectors hence the lazy timing Link to comment https://www.sau.com.au/forums/topic/441761-map-tweaking-questions/page/2/#findComment-7256739 Share on other sites More sharing options...
Badgaz Posted April 12, 2014 Author Share Posted April 12, 2014 i'm thinking of getting that turbo next...but with the bolton flange for factory down pipe.
