Title: 5 speed computer question....
Post by: vinnietbird on May 12, 2007, 04:06:55 PM
My car is speed density,and I'm using a Mustang H.O computer (AOD) to run it.I have a DA1 5 speed Stang computer in the trunk.Is it worth using the 5 speed piece instead?

I installed the 5 speed computer a few minutes ago.I haven't driven the car yet,but I'll be able to tell if there's a difference.

5 Speed eec might cause intermitten stalling at lights or when slowing down due to not having the enrichment at idle like the auto eec does.

That computer you have is from a speed density 87 Mustang with a stick. I think Dominator is right that it might cause a problem when you back off the gas. I think you would have better luck with it if you swaped over to mass air with a mass air computer. If I remember correctly Tom(TC50) knows quite a bit about the EEC.

I'll drive it tomorrow and see ho it does.If there's any problem,I'll go back to the '87 Stang AOD computer.I also have a Mark VII computer to fall back on just in case.The car idles great with the 5 speed computer,althought idling isn't driving.I need to just hit the road and see how she feels.

hey vin
i always heard you could use a manual in an auto but not vice versa.



ps did you ever find anything out about the aluminum drums?

Other way around,auto in manual not vise versa.

The manual computer is working gresat (I have an AOD),the idle is a little smoother and 200 rpm's higher.I also changed my distributor,so
I haven't had a chance to get back to the boneyard to check on the drums.Hopefully this weekend.Time has been very hard to get lately.

They say a Manual eec in an Auto car will improve 0-60 times slightly.

By the way, it is acceptable to use a manual transmission computer in an automatic car (but you cannot do the reverse). The timing curve and sensor adjustments are a little more responsive with a manual computer, giving you better throttle response and slightly improved 0-60 times.

Ardmore is in south central Oklahoma,30 miles north of Texas.

So far,the computer has been great.The throttle does seem a little more responsive.As far as 1/4 times.I have no idea.Iy'll be a while before I know that for sure.

Could be why you have that low speed bogging/stall problem.

She doesnt stall on me, just bogs every once in a while.  It's intermittent and could be caused by a slew of other things that need to be checked out first.  Many people have used the 5 speed comp without issue in AOD cars.

No issues yet.I still need to set the timing in the proper way.I did it by ear,and by feel.It's working well.
