Firmware IAC_F. I have checked the off idle TPS etc... but nothing seems to make the ignition/timing ICC function correctly so perhaps it is this sensor? Please advise if I need a firmware upgrade and if so what I need. Thanks in advance. Doug

Guys, I believe that this question was asked before, but I did not find a suitable answer. I was wondering what the dashboard CAM SYNC value is used for. I have an SFI ECU the CAM SYNC always shows up as a RED 0. I also have ICC which does not seem to work no matter what I try I can't...

Another Z Convertor I was looking though the JEGS catalog today and came across another device that does the same thing. It is advertised as being for individual cylinder control... but it also states that it is an impedance convertor as well. Doug

FYI - Z Convertor Here is a possible solution to your problem. Instead of reworking the PCM you simply put an impedance mathning device in line with the ECM. LJ is using this on his own car and is at or near 1000HP! http://www.acceleronics.com Hope this helps, Doug

Guys, I have a twin-turbo small block 375CI motor that makes over 1000HP w/20PSI of boost. So I have already got a huge fuel system etc. I have temporarily removed the turbos from the car to combat some driveability issues. The motor still makes a shade over 500HP NA. I was wondering...

Guys, I have noticed that the TPS at idle on my car has slowly been creeping up. It is now 27 at idle. Is this too high? Does this indicate a failed sensor or some other problem? I realilze that I have to set the off idle TPS to a few above the base TPS number, but does it matter that...

Guys, Question which rev limiter should be used the FAST rev cutoff or a chip in an MSD 6AL? I have been told that the MSD has a soft rev limiter that is better for the engine. What do you guys think? Currently I have the MSD chipped at 7000RPM and the FAST @ 6800 RPM. So the FAST is rev...

One more important piece of information. The car is a manual shift and has two SSQV BOV's. I have been told that the BOV may account for the black smoke. Something about the MAP pressure changing to rapidly for the computer to compensate and hence the black smoke for a second. Does that make...

Guys, I have been working with my fast setup to get it tuned for the street. I have 84LB Injectors 375 CI SBC 1000HP @ Crank Etc. The car seems to run great and is very clean on Accel and WOT but when you dump the throttle it somes black something terrible not OIL smoke, but rather black...

Okay I see how you got .850 off I don't know how I would be able to get a full 2" off... also I noticed that you must be very tight between the Ford style TB/IAC and the Water Inlet. Do you have any pics of the manifold on the motor yet? thanks, Doug

I would love to see pics... please Email a few! doug@jdhcon.com is my Email address. I thought about chopping up the elbow and intake, but I need like 2.5" so I would have to chop a lot. Might even have to take some out of the center of the Elbow. I already had the MINIRAM so I thought I...

Yeah It is about 2.5" to tall to fit comfortably under the stock hood (9" from the top of the manifold to the top of the 100 Degree elbow). I really would like to keep the stock hood on the Vette. A cowl induction/high rise hood is a pain to look over especially when you already sit so low...

Yeah, As you said we had to retune the whole car, but tuning for WOT is so much easier than tuning for driveability thanks to the WB02 and closed loop/correction. The car is now totally driveable and runs great. With the current street tune it makes 675HP at the rear wheels and it is so...

Miss Resolved... set IDLE TPS Value to be one greater than TPS at idle and boost referenced the AFPR to the manifold... and wolla the miss went away! The car runs and sounds great. Thanks, Doug

Carbuff, Looks like we have very similiar motors... I have a 375CI SBC with a very similiar setup to yours... including the Vic JR EFI conversion. Mine is twin turbo'd w/PT52 Precision Turbos. I am in the process of trying a TPIS MINIRAM instead of the Vic JR. In my case it is a hood...
