wow this thread is still here? Anyway....I was wondering if anyone had an airflow output map from an RB25det setup...I dont care if its stock voltages or for a modified engine, I just need something to start from...My maf isnt working and instead of buying one to just log the voltages and then toss (have map sensor) I was hoping I could get out a little cheaper with some help from you guys. Im just now getting this car running so i never had a chance to log anything and this is the only thing holding me back....any and all that respond, it would be greatly appreciated. Thanks If your interested in my setup: rb26 style intake 660cc injectors .81 a/r turbo stainless exhaust manifold external wastegate mahle pistons eagle rods 255lph walhbro FMIC 90mm throttlebody head studds

You still have that head ? Do you know the miles or km on it? And would you ship to the u.s.? Paypal?

What are you using to to tune the injector and/or ignition maps after the clamp? Greddy pressure or still throttle postion vs. RPM? I'm sorry maybe you've posted this info already..... i have read this whole thread (took a week) but I dont remember if you have or not.

So you're still keeping the airflow output map on greddy sensor when doing all this right? and doing all the clamping there and not even using the boost limiter map?

Id like to say this is probably the best info on the EMU i've seen on the net and I've been pouring a ton of hours in searching, much thanks to URAS and all others who know what they are doing with the EMU,Anyway.. Had a few questions, Ive got a series 2 Rb25det ive stuffed into an S14, all S14 wiring gutted and nothing but R33 wiring in it. (yeah I live in the states) Ive got an EMU that I'm about to wire in and plan on doing the AFM elimination. So after I log the greddy pressure sensor vs. RPM and get as much data as possible and put that into the airflow output map and interpolate the rows and such, get the numbers looking and working good... Im guessing im going to max those numbers somewhere in that layout and hit boost cut. Ok so I clamp the voltage rite before that happens...now the ECU never sees the voltage but i still need fuel and timing correction beyond that point, soooo..... Do I go to the injector and ignition maps and put in the values i need there? or do I use the aux. map or something else? Also what if some of the values inputted into the airflow output map overlap something you've put in these other maps? which one wins?
