Please DO NOT Post In The General Section

From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.


The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

Again if you have any questions, PM me or one of the other mods.

    IAC Valves

    These Hondas all used a PWM IAC valve. This valve runs at a frequency around 500 Hz, so in MS1/Extra you will need to set the frequency to 20, while in MS2 Bowling & Grippo code you enter the number 500 directly. V3.57 boards need no modifications to control this valve, while V2.2 and V3.0 boards will need a TIP120 transistor, like the one included in our MK-PWMIAC mod kit.

      I have the TIP120 not 122, sorry about that. Somehow I misread the frequency information. I'll try that. Somehow I got mixed up on the MS1/Extra and MS 2 and V2.2 and V3 information. I have V3 and am running MS Extra.

      I feel like it's really easy to overlook simple information and start drowning in the ever complicating information and troubleshooting threads with megasquirt. lol
