JWT/ECU a fake? Think mine is
Well I have been seeing that the tach reads 5400 when the LED indicates the harlan is going off. So I did this...
When I set the harlan to 1k ... the light lit up at 1100
2k was alittle more
and so on
5k was at 5400
and my tach reads 7400 when the fuel cutoff takes effect.
So I set the harlan to 7k and it never opened up at all. I think I am going to set it to like 6900 just to see what that does. Anybody with a VI and JWT/ECU wanna try theirs like this? I dont know what to think right now.

If you are trying to guess that it's a fake, don't! Nobody else [except JWT] has been able to touch the rpm limiter. Whether it is truly 7k rpm is another question. In any case, tach is definitely off... especially in 1st gear.

still working on getting my ecu, had a terrible time got wrong ecu and had to send it back and fight for my money, but i would hate to think im going through all this to end up with some fake ecu .. im just going to demand 7200 rev limit, and then take it to the track and expect a .1 or .2 to come off my 1/4 mile times.
if it does not, then i will cry out FAKE as well ... but for now im keeping the faith .. i sure hope your ecu is not a fake because that would suck ! good luck !

Well I think the harlan might have a slight issue of this, but I was thinking about it and if my tach hits 7400 when it shuts down and then in the harlan is set at 5k and it shows 5400, that shows that its off by 400 rpm. The harlan wont work on 6900 or 7000 though. So I dont think its really the ecu if my tach is off by 400rpms. But the idle seems to be right, it slowly gets off track little by little all the way up to 7400.
Set at 5k ----> shows 5400
Set at 7k redline ----> shows 7400
Set at 5k ----> shows 5400
Set at 7k redline ----> shows 7400

There's nothing wrong with your ECU. The Harlan is just a little slow to react (100-200rpms slow). My rev-limiter kicks on at an indicated 7200rpms in 1st gear and 7100rpms in 2nd. I've never revved it to fuel cut in 3rd.

Thats what kind of got me is that I dont really notice this low end loss that is suppose to be here with the MEVI. But tach off by 400 is wild.

Yeh it was already in. And that is what I meant to say. (midrange)
So what do you guys think. When the fuel cutoff is like 6800 or 6900ish and it revs all the way, then the coil doesnt send a signal out?

And can you set the harlan to 7k and it go off?
