Need some info

So I am close to firing up my GN.......before I tore It down it had the 84 ecm in it. I have everything needed for the 87 ecm. My question is, is it safe to install it right away since I did an off chassi Restoration, or should I put the 84 ecm back in and make sure it runs?

 

[Wahoo]

It should run with the 87 ECM, mine runs fine currently with what I believe to be a stock chip for an 87 car... But I don't boost it or drive it right now and I will be getting the proper chip burned in the spring when there is no snow.

It should start and run ok but I would not go into boost!

 

[Brad_H]

Ok thanks and I have tt chip already.

Should be fine keep a look out on how the fuel is burning to prevent misfiring

 

[Brad_H]

Do I need the reburn the tt chip to run a Efan ?

 

[Jerryl]

I say . . . If new ft cam, use old ecm to make sure it starts right away, and runs to break in the cam.

 

[Brad_H]

Ya I still have the stock cam in, but still need to know if I need to re burn my tt chip to run a electric fan with 192066 kit

Do I need to reburn the tt chip to run a electric fan using the 102066 kit

 

[Jerryl]

Send email to TT to see if it's already done.

 

[Brad_H]

When I ordered the tt chip it never asked if I was running a electric fan so I never thought to mention it

 

[Brad_H]

I talked to them they said yes it will turn the fan at 166

So long as your chip is burned for your injectors and setup....you will be fine starting and staying with the 87 ECM. I wouldn't try starting it with a chip that is not right for your injectors...

K thanks, so should I use my stock fpr when first start up, I have an adjustable fpr but I haven't installed it yet

 

[turbonut85]

You could...but not really nessacary....so long as you have a fuel pressure gauge and can get it set right away.

 

[Brad_H]

Does anyone know where these lines go, a diagram would be nice. And what are these things called?

 

[turbonut85]

Pic 1--vacuum cannister for hvac. One line is from vac source (not from a source that sees boost pressure), other goes inside to feed hvac controls
Pic 2--heater control valve. Line should come from hvac controls inside the car
Pic 3--Hobbs switch for digital dash (not sure if this needs to see boost pressure or not....think it does)
Pic 4--line with the T should route from back of intake(boost pressure source) to the MAP sensor...and I think it T's into that Hobbs sw...?

 

[Brad_H]

K so on picture 3 I have 2 empty plugs, one I know is for a/c and is the other one the spare digital tach plug?

 

[turbonut85]

Looks like the MAP sensor plug...

 

[Brad_H]

Looks like the MAP sensor plug...

In the pic for installing the wiring harness 102066 for a electric fan shows two plugs, one for tach gauge and other digital , the one you said the map sensor plug looks like the digital one and the one you said was the digital ( brown plug) shows it's the tach
