im running a auto ls ecu in my manual eg.even if i do the auto to manual ecu conversion,will it still idle badly?will the rev limiter still be the same as it is?the ecu is auto and so is the motor.will i have to swap the manifold with a manual one if i get a manual ecu?

 

cmon fellas my question has to be worth one response!

 

yes it will if u have the auto manifold u need to do the IACV fix. Because one of the wires on the 3 wire IACV go to the auto plug.

 

so how do i fix it exactly?

 

Just buy a manual ECU in the first place....

 

 

oh okay i see my bad

 

its all good bro.

 

hold on. are you running a manual tranny? id say if your running a d series engine use proper ecu.

 

no im running a ls motor with ls tranny and auto ls ecu.the motor is an from a auto car but mated with a 5 speed tranny.i would swap the ecu with a manual one but id have to swap the manifold with a manual one too right?i can do the auto to manual ecu conversion but as jimster said ill still have to do a iacv fix.so my question is:how do i do the iacv fix?if you have a easier setup that you recommend then shoot.

 

there is a wiring diagram for a IACV fix on the auto harness. It takes a 3 wire and turns it into 2 by combining 2 wires on the harness. I have the diagram for it somewhere. You can also put a patch in your TB to bypass the IACV.

You said you're using an OBD1 jumper harness, your stock OBD2B auto harness, and an OBD2A engine. Your problems most likely lies in your mish-mash of wiring. To start, you can use your OBD2B auto harness, but you need to do the IACV plug fix. Read this:



The OBD2A difference of the engine doesn't matter and your engine harness plugs into all the sensors fine.

is this the iacv fix?let me clarify this so i dont screw up.if i do the iacv fix i HAVE to use a manual ecu.can i do the iacv fix and still use the auto ecu without having the idle problem?

 

Also,can i just cut the orange wire off of the 3 wire plug instead of getting a 2 wire plug and splicing.

 

lol really? ima do this fix. That way i dont have to get a manual manifold.

 

lol u have the same problem?also i cant run the auto ecu after i do the fix right?

 

might wanna check your dizzy and make sure your timing is good that could cause rough ideal.

 

no its the auto thing because ive heard other people have the same problem when they do auto-manual swaps.

 

gotcha man good to hear you figured it out

 

ya i have a crazy *** idle on my conversion. It starts around 2300 and finally gets down to around 1200.

 

yeah pretty much same here.i can do 35mph just idling but it starts to kick back and forth when the idle starts bouncing.

 

thanks man

 

ya mine just goes from like 3200 to 1000 and then goes lower sometimes. its just retarded as **** sometimes lol.
