Wiring MSD 2-step to oem coil
 

. so i've searched long and hard and im not getting what i need.

i've heard its possible to hook an msd 2 step to the stock coil but i cant figure out how. it only has 2 yellow wires w/ a 2 prong connector for the rev, and a 12v, and gnd.

also do you have to run the 12v to the clutch switch with a relay and momentary button? or is there other ways of doing this.

id love some answers im ready to go out and put this thing in if i dont have to buy a full out msd ignition

u do know with crome u can do a 2 step also its a lot easier

im guessing hes running a fmu or some afc hack not a real tuning program

prob, dont even know why they sale those things anymore. for half the price u can get chrome put in and tuned,well atleast around here u can

no im running n/a as of now. not putting the turbo back on till i tune it. i have a chipped p28 ready to go in with a hondata s200. . no idea what options are on it. im guessing no 2 step... the guy i got it from got it in a car that he bought. so he never messed with it. ..and before you bash the s200, i paid 100 bucks for it and a chipped computer that i already sold and made more than my money back. so it was free basically.

i have an msd 2 step with 2 rpm control modules that i paid 50 bucks for.. and was hoping to wire it in some time this week cause me and some ppl are goin to the strip tomarrow. (wanna see what my d15b will run n/a).

what exactly does "crome put in" mean. i would search but i gotta leave here in a min.

with my hondata setup there is the interface (s200) .obviously, but im not familiar with how crome is ran. i was under the impression that you just chip your ecu and run the free-ware program with no actual box interface. and just tune it with an emulater and such.

and idk bout your fmu statement. fmu's are dirt cheap. my vortech that i ran when it was boosted before cost me 50 bucks. so idk how you'd chip a ecu and have some one tune it for cheaper than that... let alone half. but hey if you can give me some info. i wouldnt mind ditching the hondata and goin crome.

this is how you do it step by step:
get a chip and zif socket-30
solder socket in
get a chip burner -90
download crome-free
use crome to changes settings
done

really

ohhhh.. k im buying a chip burner now. ---- the hondata... i downloaded crome awhile ago so i'll give that a whirl. ...

Once i set the launch rpm for the 2 step its un-changable obvisouly. Anyone have any idea is you could hard-wire an msd rpm control module to the rev to be able to change it?
it is only 2 wires...

ok crome says it can add "extra features" like 2 step blah blah blah to obd1 P30 and P72? what does that mean exactly.... i have a p28 and planning on starting with a p08 basemap. how do i activate that feature on crome?

htere should be a little box you check and when you check it it should have a place to set the rpm limit and speed. i had mine on my crx at 5k with a shut off at 8mph. i dont have crome on this computer im on its on my other computer but it should be there.

yea i still cant find it... i dont think my crome plugins work... i click "add features" and a black box with a pic of a tach comes up and has info on what it is. then i click "next" and nothing happens....

you have to use the p72 bin and import values for whatever map you need IIRC.

Edit: I just tried it, you have to open whatever bin you are going to use (say p28) and go to file/export tables, that should save the values from the p28.bin to a new file.

Next you open a p72rom and go to file/import tables and find your p28 bin file and import, wala that should change all your values and now you can add all your additional features and boost tools, the aditional features menu can be found under View/Options.

basically the p72 and p30 roms are the only ones that support all the additional ---- for some reason, so you have to use one of them if you want to use all the cool plugins.

sweet thanks i'll give it a try

wire it just as you would wire it to a msd coil but in the dizzy

for the record the ecu rev control cuts fuel the msd 2 step cuts spark. I use a 2 step because I need to make boost but still stay under 4500rpm so I can launch. If I was to use the rev control no boost but with the 2 step I make 10 psi because all the extra gas is getting dumped into a hot turbo just my .02
