Greddy speed limit cut installation - Toyota Yaris Forums

47_MasoN_47 · 04-17-2013, 04:15 PM

So I bought one of those Greddy speed limit cut boxes. Planning to wire it in at the same time I proper solder all my boost wires in. Seems pretty easy but it claims in the instructions that you can use one of the wires to control boost by what speed you're going. This was intriguing because I've been looking for a way to get boost to work while in cruise control. I'm just not certain how to make this work with the Blitz, or if it even will.

Any advice welcome.

just be sure that you know that your cruise control will not work with the cut in place so you may want to plan for that in your installation if you like to use it.

Ugh, why not?

How would you control boost on the Blitz?

It has to do with how the module fools the ECU into thinking that you are going a certain speed we (Scott and I) believe. I hooked mine up with quick connects that way I can remove/install it with ease since there is no need for it on public roadways.

Ah, well yeah I guess that makes sense. Well I guess I'll dump the idea of using it to control the Blitz then as it wouldn't help anything anyway.

I was planning to install mine in a similar fashion. Do you think it would be ok to install a couple of switches in there so that (when the car is off of course) you could just flip a switch to turn the speed limit cut on or off?

^ yeah you just need a SPDT switch if it's only one wire.

I had talked about it with Scott at one point, but forgot what the answer is.
