So, for the last four days, I have been working to hopefully cure some nagging issues that my 5.0 EFI had since I first fired it up. Since it was a modified engine, I had to chip it. Unfortunately, I was new to the EFI world and bought a chip from SCT that I thought was good. It wasn't and neither was the idiot I paid to have tune it. So, after a year (long story), I finally got a chance to make some changes. I wanted to share them for any of the other EFI Mavericks/Comets.
The TWEECER was the first commercial product to provide a Real Time data stream along with tuning capabilities for EEC-IV supported processors, while also supporting EEC-V based vehicles. The TW EEC ER will require some study time before diving in too deep. The one stop site for EEC tuning information. Skip to content. And Bugs, Oh My! This is where issues specific to tuning software goes. General questions about software features & capabilities are also welcome here. But if you can think of another cool feature to aide in EEC Tuning or some improvement to an existing.
A post explaining some of the issues can be seen here: So, these last four days. Replaced the speedometer cable and added the VSS (Vehicle Speed Sensor) 2. Wired the VSS to the computer. Wired the neutral/park switch to the computer. Added a wideband AF sensor. Wired the wideband output to pin 27 (EGR) to monitor the AF on the data logging software, Binary Editor. Replaced the POS SCT chip with a Moates Quarterhorse chip.
Replaced the SCT BA 2600 MAF with Ford Lightning MAF. Started data logging. (Took me a while to figure this out) At this site, under the services tab, is a description of the different steps to get the data: I loaded three different tunes today. I finally have a car that idles without stalling or dies as soon as I put it in drive.
I have step four to go. I think I'm finally on track for having a car that runs like it should. I had a speedometer cable made, guessed to short. I needed a custom one to allow a silicone heat shield for the headers and to protect the VSS wires. Wasted $75 on that. Attached is a data log if anyone is interested in seeing what is downloaded. Chip: Data logging software: Wide band 02: Car details: So, if anyone is contemplating a modified 5.0 EFI, I suggest looking at these sites and having all the necessary sensors installed to get one of these engines working properly.
I hope this saves you some frustration and money. Toughest on the wallet. The Ford unit also learns and stores it via the keep alive memory. You do need to tune with a chip if the engine is modified. I assume you have to do some pre-programing with the aftermarket set up.
I'm not very familiar with it. The only thing I will say is the stock set up does require some engineering to get it to into the car. The main issues are fuel delivery and computer location. Also, no new manufacturer is using a throttle body/wet intake set up.
Does the aftermarket unit allow you to data log? Click to expand.On Fuel Mileage: My Comet has a 408 stroker ( built by Dr.Bill) in my 74 COMET and I'm running a 91'Mustang based EFI tuned with a MOATES chip on a dyno by a professional tuner ( Tony Ganyon) here in Florida. On the last Hot Rod POWER TOUR which was 4415 miles from Florida to End of Run the car averaged between 20 and 21 MPG. This is not too ' shabby ' for a 408 stroker. Just a further thought.
Unless someone plans to go in the 'business' of ' tuning' these cars, it's probably a good idea to seek a professional which would result in a GOOD tune in a matter of hours. JOO Cometized (Chip).
