Stock boost guage doesn't work after new ECU

[byebyev8]

I have a 93 auto tsi and I just got a 91 laser ECu and now my Stock boost guage doesn't work. I just wanna know if there's anyhitng else that isn't working because I rellly don't care abotu the stock boost guage

That's not a good sign. Does your boost gauge work when you put your old ECU back in?

Are you sure the new ECU is off a turbo?

You missed the point. The fact that it doesn't work is an indication that something bigger is wrong.

really I thoguht that it might do that if I got a ECu from a older talon I'm prett sure its a ECu from a 91 turbo laser cause the cars runs prefectly fine. And I boguth it from a guy on here. Yea but the stock guage doesn't work.

Check the part number against this ECU list and you'll know what it is for.
All the turbo ECU's output the boost gauge signal on pin 3. The non-turbo ECUs don't. If it is a turbo ECU then it has a problem.
