Good stuff TC!

Nice work indeed - that magnifying glass desk lamp is moving to my "shorter" list.

Nice work indeed - that magnifying glass desk lamp is moving to my "shorter" list.

me too, I caught myself doing the wave (you know, moving your hand with the object up and down like you're waving) trying to read ingredients on a bottle of spaghetti sauce

Nice! That work station looks a lot like mine, must be the red back drop =P

Notice my brother doesn't have a static mat, and he's been soldering ICs on circuit boards since 1974.

[dieselgeek]

no static mat here but it sure won't hurt anything to use it, especially in a dry climate. Keep going TC!

My house is a static nightmare. I insist on having one. I get zapped reaching for about anything.

[squirrel]

carpet? yeah, you should worry about static!

[STINEY]

My house used to be static-hell in the wintertime, until I burnt all the carpeting and refinished the 150 year old wood floors.

Now I can't even static shock the cat. Bummer....

Thanks for the encouragement guys!!!!........funny thing is I was up pretty late last night doing most of this and couldn't understand why the nylon screws that hold the MAP sensor to the board didn't tighten down right(was the last thing I did)......That's when this morning when I looked at it I realized I put the map sensor on the board upside down!!!!!!.......Ya oops, I'm sure glad I got a desoldering tool, I just heated up the solder and sucked it out and then removed the MAP sensor and flipped it right side up and soldered it back on......

So saying that make sure to double check your work and look at the silk screening on the board as it tells you how the components are suppose to be placed.........

Cool thing is it looks like they have a Pin Out list for my car on DIYPNP website, they also seem to have base tune files that are suppose to at least get the car running, but they advise that further tuning will be needed...... But for now, I'm going to double check their Pin Outs with the ones in my manual and then start installing the jumper wires......

[TheSilverBuick]

Lego's for adults I say.

Thanks for posting TC

Nice!! I'm really enjoying this one.

Ok, I got a couple of questions, one is it shows a Knock Sensor installed on my motor and there is a pin out in the manual for it on the factory computer......But when looking at the Jumper list on the DIYPNP website it doesn't seem that they are hooking it up.....I do know the board has a Knock Sensor area.....So I guess the question is why didn't they hook it up and do I really need to have it and if so how hard is it to hookup??

Second, there is a footnote for when hooking up the Injector jumpers, it says,

The factory fuel injectors for this vehicle are low impedance, around 2 Ohms each. The injectors are wired back to the ECU in two banks on ECU pins 58 and 59. We used two 10 Ohm 25 Watt resistors, one for each injector bank. The wires would be run from INJ1 out to one side of the first resistor, and from the other side of the resistor out to connectorboard pin # 58. You would duplicate this circuit for INJ2, and finish at connectorboard pin # 59.

So just to clarify, I add a 10 Ohm 25w resistor to the jumper wire for the INJ1 and INJ2 jumpers, right??

[TheSilverBuick]

Most people don't seem to tune with the knock sensor (I haven't yet gotten mine to do anything useful =/ ). I don't know about the Ford's but the GM's knock module puts out too high of voltage for the MS to take in, so a resistor and diode circuit has to be added for it. The input for it is somewhat a generic input, so I don't really know if it's been repurposed on your PNP kit. Hopefully Matt or Scott know.

From the sounds of the directions, are you sure there isn't already a resistor installed on each bank? Easy enough to check, just start from the pin and follow the lines on the board back through the MS to see if a resistor is in line.
