Aftermarket FI options for Type 4 motors 2056 or larger, Who here has gone this route and is it worth it? What options do we have? Options

[DRPHIL914]

i started looking into this 2 years ago when i was planning my rebuild motor after the drpped valve seat on the OEM motor.
I ended up building a nice 2056 with increased compression, brand new heads, counter balanced crank and of course the cam is performance minded as well.
to start i installed the d-jet and later last year i added a 50mm bored out stock throttle body from Tangerine/Chris Foley. Yes this helped a great deal, but we are still limited due to the d-jet and the MPS. So there are a few people out there that make ITB( independant throttle body) that could be used.
One is Jenvey, and i see that PMB is carrying those. It looks ike they are mated to what ever IDF intake manifold you choose. there are 40, 45, 48 options. mated with 350cc injectors.
I am wondering other than the CB performance stuff that has been available for a while, others have come to the table, who here has played around with this ? over the years ive read a lot on others using the megasquirt and micro etc and it seemd they were very difficult to tune and set up with lots of problems, trial and error.

I am looking for advice on what to stay away from and what are the pitfalls and mistakes we can avoid before jumping into this.

Look forward to some input, thanks!!

I have the Dub Shop kit on my 2056. As delivered it was easy to install and set up, and it started and idled on the first attempt with the default Type 4 tune file Mario included. After one dyno session I consider the tune 90-95% complete. I hope to get the remaining 5% this summer as I learn how to tweak the Megasquirt settings.

thats awesome!

So the Holley system is what PMB has now gone to , you can use stock components for intake ant TB or go with manifolds and ITB . either way you have a new self learning ECU and new injectors and coils that are basically stock for a small block chevy, they are making the modification brackets for the modern new Bosch TPS and temp sensor to be mounted on our existing plenum . much easier than having to deal with the linkage issues for running separate bank of ITB's. also better to have the air temp and flow measured from one TB than multiple.

I would assume that the new system runs high impedence injectors so new ones are necessary but previlent and cheaper. This could be the quick and easy swap 914 ownders have been looking for with a FI system for less than a set of carbs.

So what's your plan Phil?

@rgolia
my plan now is to work with PBM to source the conversion parts they have developed, adaptors to mount the sensors, obtain the FI ECU(Holley) , and for now will
using the stock intakes and my 50MM TB on the stock plenum.

once ican do all that i will save up to eventually get the ITB from PMB(JenveyHeritage IDF 40//45)
