So I've been looking around and noticed that the JWT450 kit uses a cobra MAF to run the car. It says to run a 1993 Ford Mustang Cobra MAF This thing needs to flow at least 450rwhp, which is my current goal. Will the Cobra MAF be sufficient enough to flow what I need it to? The thing is, there are a ...

With the Z32 MAF, I have noticed that when doing a boost leak test, at around 8-10 psi the mass air flow "box" at the top of the MAF starts to rise up and OFF the MAF "pipe", which made it leak a TON of boost! I used a few large zip ties around the assembly of the MAF and clamped...

Its been a few months since the last post... any free time to implement this feature yet????
I would LOVEEEEE to have this feature!!!!!!!!!!!

Ok! I got my car running DAMN good... Ended up being the K value and Latency was off... Under cruising, I have my entire Fuel Table's set at 0, and I am getting 13.5-14.1 AFR's throughout the RPM range (low loads) Under boost, (TP of 45 and above) I have the fuel maps set at a AFR value of "8.5...

I am using Impedance of 700 at the moment. K value is @ 245 I Believe. I am getting NICE and consistent AFR's cruising (value of 0 in the first 4 load columns regardless of RPM) and im getting 14:0 AFR's across the range EXCEPT low LOW loads and idle! @ idle im getting 12.8-13.5 AFRS (Fluctuates) @ ...

I have a low-impedance driver in my ECU. 88 and 89 were the high impedance!! (not using any resistor packs)

So I have low impedance injectors with the low impedance drivers!

I think you have mistaken.

Yea sorry about that I hope I didn't thread jack!!!! Im using: DSM 450cc Injectors Z32 MAF (BLOW-Thru!!!) Walbro Fuel pump Aeromotive A-1000 FPR (set base pressure @ idle to 40psi) 87na ECU with Nistune a LONGGGG time ago (last year) matt told me to use "1390uS" as a good starting point fo...

set your entire fuel map to 14.7 and then set the k value for best results in the 2.5k to 3.5k off boost. reset fuel map to 12.5 and do it again. at this point the wideband will tell you if the latency needs to be changed in the idle - lower rpm ranges. after you have the idle set up, increase your...

stop working in AFRs and work the maps in 'Filtered values only' Now enable the 'Flags' and tell me what you see You will see 'Filtered values' in the section where the flags are enabled. Try working it manually (without autotune for now) and scale your fuel map between 0 and 127 inside the filtere...

I haven't set-up the load scales yet, I do know they are EXTREMELY high. I hit 0 Vacuum @ TP 45, and 6psi of boost @ TP 60. 6psi is all im running so DIS-REGARD the TP scales above 60. I'm not NEAR worried about the TP scales right now, im just very frustrated as I am having a very difficult time ge...

I hate this. You see the fuel map? (pic below) Please look between TP scale 12 to 30. IGNORE the rest above 30. 12 to 30 has been "auto-Tuned", I did not TOUCH the Air fuel ratios. And talking about 4000rpm and below as well (4000 and up dont worry about) ALL the cells from TP of 12 to 30,...

My car misses as well.

VERY VERY little.
its CERTAINLY not a miss from the engine.


Its a miss that occurs every 3-6 minutes, (randomly) and it will just hic-cup, but it is SOOO MINOR of a problem I will NOT and am not going to try to track it down.
Its the same miss as your describing.

VERY useful information Matt!!!
I will try today and see if I can get this thing going.
Thanks!

Ok now try setting "o2 feedback temperature" to 205 temp.

Burn it and try again.

Im suffering from the SAME problem for the past.... damn... LONG time! I will have a PERFECT tune, and then right when I drive everything will go down the shitter for a good 20 miles (MID 9 AFRS!) and then all of a sudden it will change and I will have PERFECT AFR's! Im still battleing this issue, b...
