So, since I finished my 4G63T swap, my tacho hasnt worked properly. It's fine when free revving or cruising. But as soon as you put the engine under load (eg boost..) the tacho drops to zero and stays there until you return to the previous state.

It also doesnt like to work below 1000rpm. I tried switching the ignitor and coils. 

Thoughts?

try swapping the complete dash to see if the tacho is the issue ...or problem is elsewhere

The entire cluster assembly you mean? Interesting that it only started doing it after the engine swap though. I'll see if I can find a cluster/tach assy

Note, if anyone has a mivec 1.6 10krpm Tacho let me know

Yes thats what he is suggesting..to swap the cluster and eliminate that as the issue.

[BMGTZ]

There are several clusters at my place

But no boost light?

Nah, cluster doesnt have one. Thats why Ive always been slightly dubious about the km.

Wouldn't be surprised given these cars are now 20yo. Condition/maintenance records are more important than kms.

if it doesn't have a boost light it's NOT a gsr or evo cluster you probably have a sohc cluster and damage the tacho coil with the wrong signal. Maybe.

the series one GSR had the boost light....series two didnt

Lol.

[leadfoot]

why LOL you do know i have a gsr cluster right? it has the turbo light it's doesn't work because it's not wired but it is indeed there.

[evo-gsr]

My head hurts...you have just posted 2 different things which arent related to each other at all....?
Brians answer makes sense however.
