Hey fellow SC enthusiasts I converted my auto 92 SC300 to a manual, & for some reason it's throwing an excessive amount of gas out the exhaust, does this have anything to do with the auto ecu & do I need to buy a manual ecu, or is it something else? If it is something else would u please let me know what's the cause for it or if you think you know or have an idea what might be causing the problem please let me know thank you I really appreciate your help. Either way do I need to buy a manual ecu for my car?

 

PM Algia best deal I know of.

 

honestly, i don't think you need a manual ecu. My MKIII w/2j runs with an aristo ecu (which is an auto only) and I have no problems whatsoever.

 

Alright cool thanks 4 letting me know bro I really appreciate it, do you have any idea then why my car is doing that?

 

I've got a manual 5 speed ecu for sale.

 

What's your set up, 1J/2J? What Engine Management are you running, sounds like your dumping too much fuel(running too rich)...Did you make any other changes or did you only just change the trans?

 

Did it happen RIGHT after your manual swap?

 

How much for ecu?

 

I got a 2J & I didn't do anything else just the trans.

 

Yea that's why I thought it had to do something with the ecu.

 

i just installed a full aem standalone so i've got a 92 5 speed ecu for sale if you were still looking?

 

$120 shipped and my paypal is gabutin1@yahoo.com

 

How much for the ecu?

 

So then changing the transmission to stick & leaving the auto ecu has nothing to do with the car throwing an excessive amount of gas out the exhaust?

 

ECU does not matter between auto and manual. auto toyota 2jz NA and turbo ecu;s are ran perfectly happy in manual mode, maps are same when you ground the pin for it to be used with 5mt

you may be dumping fuel due to coolant temp sensor, or some other issue caused during the swap (accidentally)
