almost finished b20 swap, but i got sent an auto instead of a manual. can i run my car off of it? some people are telling me it will run but will just throw a code. others say it will mess up my car badly. any help appreciated

 

I'm not sure, but why not wait it out and order a new ecu?

 

It will run fine.

I was running an automatic ECU on my boosted LS. You will throw a code 1660 (which isn't a "normal" code listed). It is one for the automatic shift soleniod. Your car will run fine with that code.

It throws the code because you have to have the shift solenoid in the PARK position in order to take the key out. I suppose the car finds it odd that it is driving in the PARK position, hence the code.

 

just a thought i had, i probably will end up buying a manual. i just wanted to know how bad it is to run an auto ecu. im getting impatient with this damn b20!!

 

minor surging of the engine at idle. otherwise will run perfectly fine in most cases

 

thanks shamoo, my broke self doesnt feel like spending another 100 bucks on another ecu

 

why would it surge? just curious

 

Not sure if its different, but when I converted my auto to manual it ran just fine. But as stated before it will throw a code. There was no surging, but like I said this was on a d16z6

 

ive been running an auto p28 on my sedan for over a year now. never had any surgine problems. but i do get the CEL for the "lock up control solenoid" it doesnt affect the way the car runs so i said the hell with it.

 

just open the ecu and unplug the top circuit board, thats what controls the tranny on the autos and you will be fine

the surging is from the computer trying to regulate the stall in the tourque converter

 

gotcha, thanks for all the help guys

 

why cant you call the people you ordered it from and tell them they sent you the wrong one? Ive heard of some people getting them replaced... anyways, just a thought.

 

Just run a chipped obd I ecu. Save yourself a hasle. There are no obd I b20 ECUs right? If it was obdI it could be chipped in like 5 minutes.

that doesnt sound like a bad idea actually. so you're saying get a chipped P75 ecu? just waiting so long to find all these OBD1 LS parts i want this swap so badly. im sure some of you know what that feels like

 

You don't have to run a chipped p75. You can run p05 or any obd I ecu you can get your hand on. Just make sure you get it chipped with some b20 program from uberdata or some stuff like that.

Is this true? I am having a surging problem in my manual d16a6 running a auto p28 ecu. Can anybody else confirm this?

I want to make sure this is my problem before I go out and buy a new o2 sensor.

 

I had a chipped automatic p28 on my manual civic that caused a surging idle. After converting it over to a manual ecu by removing the resistors it ran fine with no idle problems. Then again it ran fine as an auto ecu on another guys manual teg so... this may or may not help.

 

Cool. Right now I don't have an obd1 o2 sensor, and I was thinking that might cause it, but I'm going to be running a innovate wideband, and don't want to have to buy a stock one to figure this problem out now.

Anyways, anybody else have a surging idle with a auto ecu in a manual car?

 

Hey bro I have a chipped po6 2 step etc off my eg hatch that's auto will it work for my ls integra that's a 5 speed ??
