ECU auto or manual

[coupe13]

so i am doing a auto to 5 speed swap in a 91 doch motor and want to know what ecu to use. i was told that the auto ecu is better because of no rev limiter/ govener. any help please????

[fran13]

yup just stick with the auto ecu like u said no rev limiter.... or unless u want one just go with the manual ecu.

[coupe13]

if thats true then wouldent you blow the motor?

[khmer1]

im wondering that also

[duffman1278]

Why would you blow the motor?? Just because you have no rev limiter?? Just don't get rev happy, simple as that, know when to shift.

I think there is still a rev limited, just no speed limiter. I kept my auto ecu and no issues. :bigok:

[coupe13]

thanks i will just try it out for my self

Yup no speed limiter, but it still has a rev limit. My auto ecu worked fine with my 5 speed swap.

the worst you get is a high idle sometimes.

just make sure u get the same yr of your car


ex


91 manual ecu to auto 91 ecu


murda - its normal itll idle up to 2k then itll come back down to 900 rpm

theres no way to adjust that to normal idle right?

[coupe13]

ok thanks any more pros cons for the auto/man ecu

maybe you could adjust the idle but i dnt know how. but i never had problem running it like that. been driving with auto ecu for 2 yrs now no prob :D

[eulalia]

what about if you have a sr?

can you still change it to a auto ecu?

im guessing you cant?

or other then cutting the 5th gear wire how can i remove speed limit.

Mine will idle at 2k if i have it in gear and my foot on the clutch...sometimes...it hasn't done it in a while though.
