Can you provide some instructions how to wire up the fuel injector and map sensor lines into the ECU? I’m not saying it can’t be done right, but there is always the possiblity of error.

It would be much harder to tap into those wires right under the ECU and it would be on the opposite side of the engine bay which would require longer wiring as well. This is why most manufactures recommend that a 1: I was pretty surprised by the results!

Some of the factory wire bundles might be shielded, I haven’t taken them apart to know for sure though. No, create an account now.

Change out your oil after every 2 track events which equates to once every 4 mths for me 4.


Aquamist HFS-2 PWM meth injection system installed – review & pictures

When it is below 80, I can hit the normal 21 PSI. How is it holding up?

Lets just say I have a lot of first hand expereince repairing things like chopped up harnesses on cars and bikes that ran like crap because people fubared the wiring on a critical harness. Also why did you take out the trunk button and replaced it with a switch for meth? It was a lot of fun It’s incredible how responsive the system is, the injection flow follows the accelerator pedal precisely with no delay whatsoever. I know I have been thinking of getting on of these with all the heat lately.

On the regular GIAC Stage 2 map things seem to be improved subjectively speaking, the 3rd gear seems more powerful and the 4th gear is really improved. A general rule of manial is that an engine will output one percent more horsepower for every 10 degrees intake temperature is decreased.

Could the controller fit inside the ecu box? I’ve have mine half installed at the moment.

If you just twist wire and tape it, then you are most likely going to have an issue. LS1, LS6 powered Rx7’s.

I could have sworn, a long, long time ago, that Lucky IPD calculated.

A bad connection is always possible, but if you do the job right there is no reason to be worried at all. I’ve seen enough chopped and modified harnesses for V6 Toyota Mr2’s.

Last edited by blot; at Currently, aquamist is the only company that uses a PWM-valve delivery method. I ghetto rigged a wi system back in wih a pump that looks just like the one here, a boost switch from napa and some nozzles from aquamist.

Aquamit Posted by cnic Congrats on the kit The only part that should be mounted in the engine bay is the FAV Fast acting valve and flow sensor which comes mounted together as a single unit as per the HFS-3 manual.
