I am using purple and brown wires from the left side of the box. I wonder if I should use the white wire to hook up to the distributor plug. Maybe the EEC cannot see the signal.
What wires do you have the MSD connected to?

Btw, if I want my engine to drop RPM slower in between my shifts I want LB/min on the right of the scalar less or higher? My RPMS fall like a rock and my shifts have to be very quick unlike my 2003 Cobra.
Lower numbers in the right column will cause the RPMs to drop slower

Do you have the 10 pin extension harnesses installed? I had a similar issue years ago. After I installed the extension harnesses the problem has never returned.

Re: Random IAC opening...Gremlin!!

Yes ratch is what the computer thinks is closed throttle voltage. What typically happens is the TPS voltage intermittently goes low from either a sensor or wiring issue and the computer thinks that low voltage reading is now closed throttle voltage. So now when the issue goes away and you are back a...

Re: Random IAC opening...Gremlin!!

I doubt it is in your tune. I know it's a pain but I would datalog TS, ISCFLG, TP, RATCH, ISCDTY, DSDRPM and DASPOT. What I think you will find is ratch drops below the normal TPS closed throttle value and you get stuck in dashpot mode.

Re: Diagnostic Correctness: Open Loop at Idle?

It is normal for the heavy duty trucks to run in open loop at idle. The oxygen sensor is mounted so far away from the engine, it will not stay warm enough at idle to function correctly. Canister purge at idle is probably normal. Your read out shows the map reading 10" of vacuum. This seems really lo...

Re: feedback spark a9l

I just looked at the hardware only tune and datalog. You are stuck in dashpot mode because idle air is not dialed in. You can either dial in the idle air tables or go with mechanical idle. https://www.efidynotuning.com/idleair.htm The datalog shows in gear at one point. Is this an auto or manual tra...

Flex fuel sensor only sends ethanol content to PCM. The sensor does nothing else and unplugging it will have no effect.

If you unplug the electrical connector from the suspect injector and fuel continues to pour in that cylinder that injector is mechanically stuck open. You would need to replace that injector.

Re: Will not idle unless throttle is all the way to the floor

I took a brief look and do not see anything obvious in the tune. I would suspect a mechanical issue. Ignition timing, firing order or bad fuel. Have you checked compression? Also check all your intake tubing. Possibly even a vacuum leak.

Lambse is what the EEC is commanding and when in closed loop a Lambse greater than 1 means you are too rich and the EEC is trying to lean it out.

It is not possible to reflash that ECU. Unless there is a chip, quarterhorse or tweecer in the J3 port, the ECU would be running the stock tune.
