iecku.tavea racing Posted June 7, 2017 Report Share Posted June 7, 2017 (edited) HeyI am currently tuning a R33 GTR. I am using the modeled fuel model to calculate fuel on this project.If you look at the log i am running out of fuel above 4,5k (tip-in hasn´t been tuned yet). I think it is a bit strange, cause the inj duty is only 55% and i already hit the fuel table limit with 150.On the first look of the fuel tables shape i would say it is a hardware issue, but if looking on the data i would say i need to rescale the fuel table. But i haven´t found a way to do something like this. It would also make no sense, cause i thought the modeled fueling will generate a true VE map.Perhaps somebody has an advice for me. :-) patrick kein sprit.llg Edited June 7, 2017 by iecku Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted June 7, 2017 Report Share Posted June 7, 2017 My map had high Ve numbers when the dead time values were too low. I'd also look to see if your differential fuel pressure is dropping. Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted June 7, 2017 Report Share Posted June 7, 2017 needs a fuel pump id assume, as Ducie said.I have seen this happen over and over. People love the nismo pump upgrade and wont believe anyone when it comes to needing a bigger pump. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 8, 2017 Report Share Posted June 8, 2017 I agree with the others here, appears to be a fuel press problem. Note also the stock GTR has FP speed controller(s) so if they are still connected make sure they are configured and working correctly. It appears there are 3 speed modes controlled by two aux outputs. There is some info on set up in the help file if you need it. Quote Link to comment Share on other sites More sharing options...
