Wow i didnt see that AT ALL when i looked. Thank you and nevermind me lol

Can i run both grounds for these couls to the same place? I dont have a signal ground back to the ecu and would like to ground them both at the engine.

Perhaps some filter caps would be ok?

would i have to buy a new registration code or can i use the old one?

is there any reason i couldnt use an igbt to trigger the 5v pullup? i just bought a 3 wire pwm valve controller board from glens garage, and it comes with two ignition drivers.

well poop. i will just have to make a circuit to switch that around.

How so? Doesnt the edis module ground the coil to charge it? Isnt that the same thing that the ls coils do?

So the ls coils' ground the signal line to the main 12volt ground in addition to the signal ground? Whats the difference between applying a 5v signal to them with a hardwired ground and switchig the ground with a hardwired 5v applied to the signal? O

The edis module would be grounding the 5v signal line, which shouldnt have any amperage to speak of gking through it. My question is if the ls modules will fire this way. Grounding coils and injectors seems to be the common denominator in engine management systems, so i think im right, or at least ...

anyone? ive read mention of doing it on here with v8 engines, but i have yet to find a sucess story on the matter.

When i say ground coils i mean the trigger ground. I know how to wire the coils so no worries.

Ive been searching, and i have yet to find a legitimate reason i couldnt do this. If i wire the vref to the ecu signal power and ground the coils through the edis module, wouldnt this work just fine? Any reasons why it shouldnt? I assume the vref line is robust enough to handle additional logic ...

My particular engine is a v4 with a 180 degree crank. I need 4 ignition drivers with this bike, thats why im keeping the stock ign module. Plus the crank pickup is weird, and i cant change it because its built into the starter clutch mechanism. I was thinking maybe a 555 timer set to trigger a ...

How do i limit dwell from the stock ign mod if its higher than 8ms?

I want to put ls coils on my bike. Are they fired just like a standard coil, but with a low current 5v signal? If i were to wire them to my ground switched ign module with some kind of 5v regulator in the switched lead to the coils, would that work out alright? Im keeping stock ign and ...

can i ask whats wrong with the cis injection? i personally think it looks cool, and was going to put it on my old school honda civic, until idecided that i might as well use the injectors that are already on my engine...(a20)

apparently a 50m throttle body will get me to 144 horsepower but is that at my redline?


are there any formulas for accounting in my higher redline?

as the title states im going to put a single throttle body on my VFR and i need to know what size to use.

engine specs are 748cc 11500 redline and i think its 100hp but i dont know the peak.

i searched for the math but couldnt find it anywhere...

i have the throttle bodies off of a GSXR 600 and there is no regulator on the rail. only one input.


does that mustang pump go in the tank?

well, i figured it out. heres what i did.

i used the factory ignition module in the wheelwell. i removed the signal for reference pulse from the mocule thats controlling the ignition to the ECU and ran it JUST to the megasquirt and grounded the low line. (just like it shows for GMDIS setup pages) i ...

i have been informed i may need to install a FET signal booster into the reference pulse line cause im sharing it with the MS. is this true? it seems like a plausible concept.
