Re: Tuning for boost with stock pcm?

the PCB was expensive... It was $680ish. To me, it was well spent because I was able to have the FAST system up and running in minutes, got rid of the stock PCM (place to mount the FAST), and I had no wire splicing to do.

I already had a used FAST ECM w/ WBO2 sensor to go with it. You can probably get used for around $900 bringing your total setup to around $1600. It's steep compared to megasquirt, but the time saved was more than worth it.

Re: Tuning for boost with stock pcm?

For less than 2000$ (or right around there for all new stuff) to have a plug and play setup that has better controlability all around than the stock setup, and still retain all dash function, etc... seems worth it to me.


I take it you still utilize the optispark?

Yup, but for the optical sensor only. I use a Delteq for spark. When I found that a new FAST splice-in harness was $350, the $680 didn't seem so bad.

I think the extra money was well worth it not to sit in the engine bay with a soldering iron, cussing at my car for a few hours. I hate wiring. 15 minute install and the dead weight of the stock computer is gone.

my MSII only uses the cap and rotor of the opti to throw spark

and i got everything you did for less than $500 ...but add in about 20 hours of work...so i guess its just a matter of how much time you have and how deep your pockets are.

So imma buy the stimulater and Complete board and wiring harness.

But since i already have a OBDII car, what will I do there on the ignition? And i will still be able to use my mallory box right?

Does MSII only watch the A/F ratio off one o2 sensor (random question i know. but jsut been reading and wondered)?

I have NO tuning experince at all.. i just know where my A/f ration needs to be generaly. But that is as deep as i know... so will i have a lot of probelms and a steep learning curve or what?


THanks for your help man... lol... at least i will be able to help others when i get this done a through with....

anyone able to answer?

you will still be able to use your mallory box, but it will have to be hooked up differently, as if you were hooking it up to a car that utilizes points.

yes the MSII only watches o2 from one sensor, you can install two with a toggle switch to go back and forth, or just assume that both banks are running the same...thats entirely your call, but as of now, its only able to watch one o2 input

it is a fairly steep learning curve, but the MSII has an auto tune function based on o2, map, rpm, and ignition readings to help you dial your tune in. do some reading at www.msefi.com and www.megasquirt.info for more in depth info on tuning, eveythign you need to know can be found at one of these two sites.

and about helpin others, man thats what this site is all about!

not tryin to be a dick, im saying this to try and help others make an informed decision about the cost of these "plug and play" stand alone systems.

Going the MS route i basically saved between $60 and $80 an hour doing it myself...about 20 hours labor, saved $1200 over your setup, and about $1600over a FAST setup...and if i did another one, im sure i could have the car up and running in under 15 hours

Will,

I already have an obd 2 timing cover that I removed for my cloyes true roller. Would I be able to set up the crank trigger with a cloyes true roller or would I have to digress back to the stock timing chain setup?

Thanks

you cannot use the gm crank sensor with the cloyes true roller, but you can use a generic small block chevy crank sensor out of any summit catalog, somethign similar to summit part number MSD-8610

too add to this.. i dont need to buy any sensors or special wiring pigtails of any sort do i? I can jsut the the stock sensors and plugs to wirign into megasquirt and im set correct?


Thanks a lot... i may have to start ordering this ****...

yes use all your stock pigtails...thats what i did

opti stays hooked up like normal so it runs the tach, but the coil is driven off the msII, so the opti is not actually controlling anything

Re: Tuning for boost with stock pcm?

How many pulses does thatwheel give? I would like a 24x signal so i can install a ls1 computer....

Ok... so to use the opti im going to use my existing crank sensor to give the signal to the MSII for spark??

lol.. cant say thanks enough.. thanks again..

exactly...and PM me when you get it all wired up, ill tell you how to set up the ingition parameters in the tuning software to make it all work
