ID2000's on pump gas on a 2.2L? NO! Whats the largest cc that can be run on pump gas?
Car: 2002 WRX
Tuner: Phatron using Romraider & Ecuflash Dyno Info: Airboy Peak HP at RPM: xxx whp @ 6400 rpm Peak Torque at RPM: xxx wtq @ 5200 rpm Baseline hp/tq for a stock on same dyno: 220 whp / 235 tq (sti) Target Boost: 20 psi Target AFR: 11:1 Fuel: 91 octane Engine/Power Modifications: bored ej205 w/ rods n pistons, injen tbe, gtspec headers n up-pipe with tial 44mm ext gate, TD04, tgv deletes, css fmic, perrin blow thu pipe, forge mbc+perrin ebcs, aps inlet, crap air filter short ram style Driveline Modifications: 2006 STi 6 speed, act street clutch, gruppes flywheel Suspension Modifications: RSR lowering springs Other Modifications: Rays Engineering 17's. NRG CF Seats. NRG Steering Wheel. NRG Harness Bar & 4 points So....I finally got around to installing the ID2000's in my WRX and discovered that they are too ginormous to run on pump gas. At 1% IDC the leanest the car would run is 12:1. I tried all of the following with no effect. Pulled 40% fuel from the MAF (AFR still 12:1....IDC still 1%) Decreased the Latency by 20% (AFR still 12:1....IDC still 1%) Scaled the injectors as 4000cc (AFR still 12:1....IDC still 1%) Set the idle to 2000rpm (AFR still 12:1....IDC still 1%) As a final check to make sure it wasnt something else in the system we popped my DW750s back in and it ran fine. Just thought this was interesting info and im curious about others' experiences. I think a 1600cc injector is gonna be about the biggest injector thats able to be run on pump gas to get 14.7 Im gonna try slapping on a FPR and dropping it with the ID2000's to see if i can get it to work.

Arent the IDC and IPW's people are seeing dependant on the scalars and latencies we/they input into the ecu? IE just because 1 person is seeing 0.50 IDC doesnt mean i will necessarily be able to accomplish that with my scalar and latency......or is that wrong? 2 - The ECU can't properly tell the injector to spray less fuel - this is also a possibility but i am still leaning towards #1 3 - Something else in my setup is wrong - Im pretty sure we debunked this when the DW750's were reinstalled and the car ran fine.
