Default Joey L’s R33 GT-R with DP HFS-4

I joined this forum way back in 2015 because I love this product and wanted to install one in my car. Lots of things happened inlife and I didn’t have time to work on my car until 2020…..anyway just want to say thank you to Richard for helping me with this amazing product and his support. And some pictures of my build/tune/idea

Little rundown of my build: RB26 260cdur 10.8mm lift, EFR8374 1.05 twin 38mm gates, Haltech E2500 with individual EGT. Haltech spits out digital signal to HFS4 and the Aquamist control housekeeping/safety. It’s 50/50 water methanol with distilled water and ethanol from local hardware store. I aim it at about 17-20% ratio to gasoline but I am still trying out different tuning ideas.

Currently running 0.5mm check valve jets on all 6 cylinders. I planned to put one more for IAT cooling but haven’t found it necessary. I haven’t really pushed the car but it’s almost like the engine doesn’t knock with the 91AKI we have in Canada.

In the referenced picture, ECU reduce fuel (gasoline) by 3.25gram/second. Assuming the mixture of water/meth is 50/50, 3.25g/s * 2 = 6.5g/s. If we divide it by mass fuel flow (6.5g/s / 38.38g/s) you get 16.9%. Please let me know if the calculation is incorrect.
