RH9 GTR Posted June 24, 2017 Report Share Posted June 24, 2017 Hello.I am using a G4+ plugin platform. Can i get flames on decel or high rpm throttle lift off using over run fuel cut ?Is there any other way to achieve it ? I have read the help file, before applying it just wanted to have your opinion.Thanks. Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted June 24, 2017 Report Share Posted June 24, 2017 You would typically want over run fuel cut off for this. And then you could enrichen the areas of the map at high RPM high vacuum. Quote Link to comment Share on other sites More sharing options...
RH9 GTR Posted June 24, 2017 Author Report Share Posted June 24, 2017 Thanks brad for the prompt reply. Can i play with the injector latency as well ? When the car drops to high rpm vacuum ? Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted June 24, 2017 Report Share Posted June 24, 2017 latency will not do what you are after danamaniac 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 25, 2017 Report Share Posted June 25, 2017 (edited) Go for a drive with your laptop connected. Turn on snake trails and watch your fuel table during a high speed lift off, take a note of the cells in the table that the snake trail moves through. Most likely it will be the very top right cornier like I have highlighted below. Put much larger numbers in these cells. You will probably get more effect if you also remove about 20deg of timing from the ignition table in the same area. Be prepared for a big hit in fuel economy after this change.

RH9 GTR Posted June 26, 2017 Author Report Share Posted June 26, 2017 I got it exactly !! Adam why are you using MGP instead of MAP ? any specific reason ? Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 26, 2017 Report Share Posted June 26, 2017 I got it exactly !! Adam why are you using MGP instead of MAP ? any specific reason ?I dont even know what that fuel table was from - it was just whatever map I had open at the time.Our general recommendation is to use MGP as a load axis rather than MAP. The reason is MGP compensates for changes in barometric pressure (or altitude) better. Quote Link to comment Share on other sites More sharing options...
RH9 GTR Posted July 1, 2017 Author Report Share Posted July 1, 2017 Ok . So other than baro compensation there isnt any significant change using MAP as load input. Quote Link to comment Share on other sites More sharing options...

I have it set to 102 on my 1uz and -20 deg timing and I'm still getting nothing lol Quote Link to comment Share on other sites More sharing options...
dingdongdrift Posted October 17, 2021 Report Share Posted October 17, 2021 I tried 120 and -20 timing and still nothing is happening. Is my closed loop lambda preventing it somehow? I doubt it though because it's reading 0.7 lambda on decel. Quote Link to comment Share on other sites More sharing options...
Warchild Posted October 18, 2021 Report Share Posted October 18, 2021 I have been asking for help on the same subject, I am have done what has been said, but I also do not get it right Quote Link to comment Share on other sites More sharing options...

Tried going lean and still nothing as well. Quote Link to comment Share on other sites More sharing options...
mldc Posted October 22, 2021 Report Share Posted October 22, 2021 Create Virtual Aux 1. Add the conditions where only Your overrun CUT might be. You can select 3 parameters which can control VA1. Create GP LIMIT 1. In the GP LIMIT 1 Table Use X axis as VA1. Values 0,1,2. On Y Axis In my example use RPM. But RPM also is in VA1, so duplicating values. Idea of working. When You are off the throttle only in overrun vaccum area VA1 becomes active. State 2. State 1 and 0 is when VA1 is off. In that area GP LIMIT1 works as RPM limiting. On vaccuum in certain area You will get Ignition cuts. Those cuts will add more fuel to the exhaust which will burn and pops will apear. In the main fuel table add more fuel in overrun area. In the main ignition table retard the timing in the overrun are. So now You migth have in the overrun are: Ignition retard, ignition cut, extra fuel. I've never done this way, but theoretically it migth work. On GP LIMIT parameters play with Start Cut and End Cut values.Do it on Your own risk, I'm not responsible for the consequences You might get over this.

You might as well just turn on AntiLag to accomplish the same thing without having to sacrifice a GP RPM Limit. Quote Link to comment Share on other sites More sharing options...
