chango- with the portfueler, the stock injectors are "clamped" at a certain psi (stop spraying more fuel, just a constant amount) and the 2ndary injectors (portfueler inj.) start spraying at 15psi...
hahn calls for the map to be clamped at 3.96 volts.. which is equivalent to ~12.9psi of boost (if i remember correctly).... the portfueler reads vacuum/boost and rpm.... once it sees 15.0psi and above, the injectors start sptting fuel based on the psi and rpm....
hope that explains your ?..
yes sir you did, thanks very much,and my clamp ranges from 3.88-3.98, it just fluctuates when the car is idleing or running.......
right on... i know my clamp is at 3.96.. it's a ptp map/tip clamp and can be clamped w/out it on the car (via an access wire that reads the clamped voltage, as long as a higher voltage is going through the circuit)...
sebring... from my experience, junk the vacuum line that goes from the compressor housing to the wastegate... pick up some silicon hose (from summit/jegs) and use that.(w/zip ties, of course)...
the clamps are pretty good, but i had a bad experience w/the hahn hose and clamp while running an sti....
car felt quicker than ever, and ripped past the sti in 2nd gear put 4-6 cars (more than a bus) on him by mid 3rd so i shut down.... i checked my "max boost" on the zeitronix and it was 25.9psi... a lil high for pump gas, especially when my boost controller was set at 16psi at the time..
brought her to well lit area and inspected.... (yanked the intake piping) to see that the hose had "popped" off the compressor nipple (so the WG basically stayed shut)
boost came on hella quick, hehe.... and my BOV sounded mean as FUK..

Do you know what size silicone hose should be used? I have about 6' of 3/8" ID silicone hose sitting in my garage right now. Most of that's for running a catch can after I get the car back from the shop... but I'm sure I scan spare some of it...
Has anyone made a custom fuel map with the Portfueler? I made a few that I'll test out later on tonight. I'm trying to keep the AFRs close to 11.8 to be on the safe side.

I have a VERY custom fuel map...I have a GT3076R and RC650cc injectors, so my setup for the 20G is history. I'm using a modified 16G map, keeping the AFR's as close to 11 as possible. I can probably make more power leaning it out some, but I already melted 1 motor and I dont plan to do it again.

save your motor...imo
cheers
right on......i have the same map/tip clamp as well......
Can anyone send me the Portfueler Base Map for the 16g? Mine got messed up by someone who was trying to tune it for me.
- Thanks
I don't have the base map for the 16G but I imagine you can take the base map from a 20G and just run really rich. From there, if you have a wideband, you can subtract fuel by using the percentage feature.
20G + Portfueler=
