xdi 2000cc injectors

[Helpme2000]

Disregard, I was able to figure out my issue

I have tried and struggled to get my car running with the XDI injectors. I have changed the injector size to 2000cc. I have also lowered the minimum pressure to 10bar, but not sure if that is correct. Put max pressure to 250bar and have the default pressure at 180. Not sure if those need any tweaking but would appreciate any input. There have been a couple of times I have got it to run for a decent part of the time but that’s it. As far as adjusting the idle fuel pressure table and the recommendation of lowering it to 10 or 15. Is that just one or two blocks or is it across the whole section of a specific rpm? So far I have only adjusted the table blocks of 13 to 10 and 16 to 15 for the 900 rpm section. I also changed the same blocks under the 1300 rpm exactly the same. I have also been lowering the warm fuel but have had mixed results. I’m probably doing it wrong and would appreciate any recommendations as I am unclear exactly what blocks need to be adjusted to get the idle correct and then I can try to worry about part throttle. Thanks

I have the same experience as you

What I found with mine was that the hose clamp on the throttle body snapped and I had a major air leak. As for the idle I dropped the first column of the 900 rpm range to 15 and the first column of the 1300 rpm to 30 and the idle works fine for me. The plus width is still not above .8 but I’m not having any issues with my idle.

can you share who your tuner is? I'm still stuck on this issue and my tuner can't help me beside going back to stock component. thanks

[Helpme2000]

I do my own tuning. 3 years ago I bought a Hondata video package from Evans Performance Academy and been doing it all on my own since. I’m pretty happy with it.

[dxiong19]

Think you can take a look at my logs? And what’s your setup?

[Helpme2000]

I don’t mind taking a look at it, but I still don’t feel as experienced as people who do it professionally or what the Hondata techs on here would recommend. As far as my setup I am full bolt mainly all PRL, except rampage 4 inch MAF housing, Hondata 500 MAF sensor, Hondata low pressure pump, XDI high pressure pump, miltec ... exhaust, AWE touring exhaust, PRL P700 turbo, skunk2 intake manifold with 2 liter spacer and have MSD ignition coils.

***** except rampage 4 inch MAF housing, Hondata 500 MAF sensor, *****

I hope your not using those two together.... that's not what they are intended purpose and would make for a terrible scale.

You must either use one or the other....

[Helpme2000]

Yeah, I have been told. I wanted to see if I could get it to work but no matter how many tries the scaling was all over. I got it to run smooth and worked decent but not as consistent or as smooth as with the PRL race which I went back too. Lastly the turbo spool was definitely better with the PRL MAF than the rampage one with the Hondata MAF sensor
