So I finally got off my fat ass and installed Hertz's Bucket Spec Evo3-16g. All that is gravy, no leaks blah blah blah. Just creeps a little in the higher gears which is to be expected. So I get things tidied up and have taken it out for a few spins around the back roads while data logging. I find some strange sh*t is happening.
Most of the time when I mash the gas, the car boosts up to 8psi and doesn't seem to be going that fast. Then all-of-a-sudden it'll take off like a bat outta hell as the RPMs get up there. Looking at the data logs I find a strange phenomenon. I smash the gas (100%), air flow increases, but the injector pulse width stays flat. Like.. dead flat, at 12.5ms or something. This it will all-of-a-sudden jump sharply, then continue up at a smooth pace like it should. So I can see that the dead spot I feel while driving is the injectors not opening up. Any ideas what could be causing this?? Although I'm tempted to not even figure it out as a have a round of mods that might make this go away. /ubbthreads/images/graemlins/dunno.gif
Only other thing worth noting is that there is a CEL 44 code, ignition coil. Not sure if there is something wrong, or if it has to do with the COP setup. I haven't searched yet, I will after I post this. Yes, I know, I'm doing this out of order. /ubbthreads/images/graemlins/grin.gif
Car drives relatively normal otherwise, save for some crappy idle. Haven't started trouble shooting this yet, but I'll wait till I recirc my BOV. That is probably causing a bit of it.
Current Mods:
Stock ECU (Caps changed by me already)
Stock Maf (On 3" intake)
190 lph fuel pump
AFPR set at 35psi ( I think)
Coil-On-Plug w/NGK BPR6ES (6 or 7? Whatever the stock temp is, can never keep the numbers straight)
Stock intercooler and piping
Stock BOV (uncrushed) vented to atmosphere ( I know, I'm too lazy to pipe it up until I get the new MAF on /ubbthreads/images/graemlins/tongue.gif)
2.5" Downpipe
3" turbo back
Evo3-16g, ported, Bucket Spec
2g quasi-ported manifold
2g O2 housing, ported
Mods to be installed:
Keydiver ECU
#482 MAF (If I can find the f-ing cable!! /ubbthreads/images/graemlins/mad.gif)
Denso 660's
JonVR4 IC pipes with Evo8/9 intercooler
Dejon style modded BOV (to be purchased)
