The best $300 I ever spent on my Jeep (includes everything). I got a lot of help from jadams68 & rjcj-8 from this forum & Bill USN-1 from the IH forum. A few more of us do this and we ought to get pretty useful helping out others. I kicked some info toward jadams68' write up. Beats $1200 for a Howell Kit.
Been running TBI and helping others for about 4 yrs. (not just IH's)
Very simple install (for most) if you are bolting it on a stock motor. Will require a new chip if running cam/headers.....
Same system as Howell, CustomEFIs and AFI. Just DIY for about $300. and you have timing and fuel control. Howell does mostly fuel only.
I've done 4 cyl and V8's and assisted on 6 cyl applications.
All using the same ECM's.
You can add another $150 if you want to program your own chip!!
Due to a server/domain swap some of my info was lost but most is on the
in the fuel injection forum.
I'm in the process of getting it all reposted.
Almost all the problems I have seen were a result of installation error or a problem with the fuel system that was there before the system was bolted on.
Go from -20* to +100* and from sea level to 14,000 ft and not have to mess with a thing!! no jet swaps! no timing changes! It just runs.
Most are really afraid of wiring.
Once you sit on the floor for a couple hours, you find out it's not that bad!!!
