there is a good post going on over at supraforums, and i was giving good feedback on my alkycontrol kit.. this guy had some insite and i just want other opinions since i think he makes some valid points and i'm not realy sure on how my system works.. here is the post from (anarkey)
So far ( to my knowledge), my kit is still the only one designed to be run in conjunction with a AEM EMS or comparable standalone ECU. The EMS activates it (not a external pressure switch) with a software programmable output. The pump reports back to the EMS that it has achieved injection pressure. You then use this feedback signal from the pump as the basis to do fuel/timing/boost changes.
Everyone else turns on the system and then you tune with the hope that it is working and full of meth/water. Some will cut boost, which I'll tell you, is NOT enough when you have tuned your AFR to work on methanol. Sure you can cut the boost down, but then you are still at 13.5-14 AFR. You need to be able to revert boost, fuel, and timing (if done), to make it safe.
I have noticed many systems that use the Shurflo pump still have the power wire going through the switch on top of the pump. BAD practice. Again, just test that setup off the car and watch the spray. That switch is turning the pump on/off about 2 times a second. You don't get steady spray. You get PULSE, dribble, PULSE, dribble, PULSE, dribble. You need to run the pump full blast when you do run it.
The reason I push the EMS for methanol use is that you leave so much performance untapped if you can't optimize the timing, fuel, and boost (ALL THREE) for it. While injecting you will often lose power on the same timing, but gain it back and more with advanced timing.
I never tried to compete with normal systems 4 years ago when I started selling mine. Now there are 4 more major companies pushing their standard systems. I'll tell you, they are all essentially the same thing. Same pumps, nozzles, hoses, etc. The occasional variable controller, which I welcome anyone to test OFF the car and observe the spray. Lets say, most of them suck. I abondoned variable control a long time ago because I concluded the spray was simply too poor trying to lower output by pulsing or lowering voltage to the pump (which is how they all work).
I know the idea of progressive sounds cool, but after years of testing and 100+ cars, I have found that a robust ON/OFF cycle with correct flow rate, and tuning for such, works best.
100% methanol also, bad idea. You can create a ignitable mixture in the intake manifold. I personally know someone who has exploded a intake on a 3000GT doing that. Please, please, run 50/50, and use the right ratio. Don't try and dump 40% of your fuel as methanol through a injection system.
If you can't have any form of tuning to go with a injection system, then run pure water and use a very low flow rate.
