Can it support peak/hold injectors on a 4 cylinder engine? I know the Accel DFI 6.0 is old...but I'm just trying to get the car running and sell it (and it would take more work trying to rewire for another ECU)... I understand it has 4 peak/hold drivers so it can on a 4 cyl, but not on an 8...

Anyone have any problems running the DFI 6.0 with 4 low impedance injectors (batch fire, not sequential)? Norbs sorta answered my question...he said he's never seen one fail...I'm just curious as to why the manual would say that it can only be ran for short periods of time...any input...

The "manual" states that: The batch fire spark and fuel ECU incorporates a series of 4 internal peak and hold 4/ 1 drivers and has the ability to run 8 low impedance injectors at full duty cycle for short periods of time. I'm slightly confused...so if I'm running this on a 4 cylinder (4...

Subject line states all...thanks.

I have a few questions, I notice that in the Edit File mode, my IGN timing map is from 1500-5000 rpms...but when I am in Edit ECU mode (with the car on) it shows a 1000-7000 rpm map!?!?! What happened? Which one is right? Because I've been setting up my base 91 octane timing maps, based on...

My external fuel pump always makes a buzzing noise which is normal...but after a long 30-40 minute (hot) drive...the buzzing noise gets VERY loud...after it cools off, it quiets down again...its a NOS external fuel pump if that helps...any ideas?

I am running the Accel DFI 6.0 but without the IAC...I haven't noticed any problems....I do idle it at 1000 rpms... I know the IAC helps stabilize idle...esp. when A/C turns on and all (but I removed my A/C)...but what else does it do??? Does it make the car easier to drive in 1st (or taking...

Is it just me or does the Accel DFI 6.0 display load in PSI for Fuel and BAR for Ignition? Any reason why? (just a little weird to me) (this is when you're in Edit ECU mode)

Anybody have problems idling with 850CC injectors low impedance (~83#)? Also, what is the typical fuel pressure you guys are running? (@ idle) I'm running 90 psi @ idle...with 1:1 increase according to boost...so about 115 at 25psi boost...I'm afraid something's gonna pop off and set my...

I can't seem to get any help on my DFI 6.0 at the MR2 board, so I've come here for some help. What impedance injectors am I supposed to get (low or high)? Is there any option in the software to change between high or low? Does it vary between different firmwares? Anyway to check? I keep...

Hi, I'm new to this message board (from www.board.mr2faq.com )...the reason I'm here is because I was pointed here for Accel questions. I don't have a Buick...or even a domestic car. I have a 2.0 L 1993 Toyota MR2 Turbo (Heavily moddified). I hope you guys are still willing to help me out...
