You'll hate my next idea.

[8valveprick]

I plan on running a DSM engine harness and ECU.
PROS:

1. easy datalogging, I already use the software for datalogging my Colt.
2. can use SAFC
3. can later use DSM link for full manual control of engine
4. CHEAP, at least for me

I already have a parts car w/ ECU and harness. I have an extra SAFC. All my friends that are smarter than me are familiar w/ the DSM stuff. I won't have to pay for a custom cal and when I make changes to the car I won't have to send my computer back for changes. My only real expense will be a Mass air translator ($200) since I will be using a blow through GM Mass air(free). I don't know what a custom cal + 3 bar map will cost, but I'm sure it's more than $200.
CONS:

1. I will have to adapt a DSM cam angle sensor
2. having to wire it in

As far as I know all I need is the injector harness, tps, coolant temp, knock sensor, O2 sensor, and coil pack. I already (with help from friends) wired my Colt this way and it wasnt bad at all. I would have to add all the same sensors to the 16 valve setup to run the dodge electronics anyway.

Sounds like a good idea for you. Should be easy. No crank angle sensor? I hear MAF fuel injection is alot easier/more forgiving to tune..

[Garret]

Could you not use the neon Cam angle sensor for that? or adapt it to the work off the cam?

We have a local DSM guy (Talon) who was first to
run in the 10's with stock lower end. Pretty stout
stuff, especialy in that flyweight.

I'm wondering that myself. On the DSM you adjust timing by moving the cam angle sensor, the one on the Neon head is stationary. I took a long look at it today and I don't think it will be hard to make an adapter. I just have to remove the magnet and replace it w/ an aluminum piece, and put a slot in it to turn the DSM unit. Then I have to make a cover plate w/ the right size hole so the sensor's O-ring will seal.

[8valveprick]

Just thought of something else. Are Dodge injectors high or low impedence. I think DSMs use low.

[Garret]

well why not use the DSM injectors?

[Una]

Low impedance

[ohiorob]

Won't the cam angle sensor be turning the wrong way on the dodge head ?
by the way I think you got a good idea there.

[Una]

How does it matter what way it turns? It just generates pulses.

They don't fit. They are shorter and fatter.
BTW: The only reason I wrote that you'd hate my idea is that every time I see DSM on here somebody gets all worked up and has to argue how much better Dodges are.

They should be turning the same way. They will both be on the end opposite the cam gears and if my memory is correct both motors spin the same direction. Clockwise when facing the timing belt side of the motor.

My DSM friend told me it would matter to the computer. I didn't ask why, but he knows his DSM junk.

Well they clearly are better than DSMs, but owning a TD is all about stealing parts from a better car to use on ours

If you know DSM computer, it's not a bad idea.

For my 16V, i'l go with flashable smec, much more easy to do, but no dataloging available for now..maybe....

Datalog with an OTC 4000E hooked to a laptop.. That's what Paul at TU did on the Dyno..
