Affordable Fuel Injection

Zila and Johneyboy...I know at least you two have AFI on your rigs. The only bad comments I can see about them is sometimes the Tech support leaves a bit to be desired. But on the whole, have you had any issues with it on or off road...or during install?

My CJ has a 360 with the Melling MTA-1 cam so it has good low end torque now. I'm pretty sure this works with the AFI tune. I'm going with the Performer manifold so the stock 2v is going away. Otherwise I think I'm ready to pull the trigger.

 

no complain about the product yet, bought a used kit from a friend who run it on a 360 too.

Took me about 1 day of install time, start on first try.

Been running it for 1 year and i didn't have any trouble at all, just the fuel pump but that not Afi related. (just dont use any blue howel). But now in the kit they sell an airtex E8094.

Afi is using all Oem part so if sensor goes bad you can order it trought auto parts.

You can buy two different kit, one with the distributor or one without. I you bought the one without, they will work the ecm that way using some electrical device (tach filter) that use the tach signal on the distributor to give the ecm the RPM.

With the distributor the Ecm will control the spark (advance) and without the dist, it will control only the fuel mix (i have this last one).


As for the intake, i have the oem two barrel and it work just perfect. Using a 4bbl intake i don't know if it will have a big difference because tbi is 2bbl. I feel a real gain over the carb in HP with the two barrel intake, so i really don't know


You will like very much having fuel injection, no more trouble with cold start. Off-road is great too, easy start when off camber.

 

How about Bill Hamilton? Hamilton Fuel Injection

If I did not do a junkyard system, I would buy one of his kits, or the Howell kit to get the CARB number.

 

Afi and HFI is likely to be the same product....price are almost the same too.

 

There was also a discussion about these guys a while back, only $800

Go Street EFI 400 HP – FiTech Fuel Injection

 

Not exactly. All three, Affordable, Hamilton and Howell, are selling the same GM Rochester TBI system that came from the factory on lots of GM cars. They are selling a mix of new and used parts that forms a kit that is tailored to a specific application. However, the GM computer must be reprogrammed to work efficiently with a different engine. In addition to the parts, these companies are selling their expertise at making the GM TBI work on an engine it never came with.

It's always the complainers that get heard ... but it's my impression that Hamilton has generated fewer complaints (ie none that I know of) than either of the other companies. Bill has been on this forum before, but his business interests didn't fit with the non-commercial rules of the forum. Howell is the only company (AFAIK) that sells a system with a CARB number, so if you need to be emissions compliant, that's pretty much your only upgrade option.

Bill's custom parts seem to be pretty nice too, and he offers a TBI to 4V adapter with his kit - this would work well with your planned Performer upgrade. He also has a reputation of working with his customers to optimize the programming by sending him a data log which he reviews and incorporates into individualized software.

 

Yez. I am in the hospital now recovring from knee replacement. When i get my laptop or home i'll be glad to fill you in. FYI I did ignition too. I had OEM crapperola. When you get to the instll look me up i can give you some tips on placement of parts etc. also upgraded gen to meet constant voltage requirment.

 

Bill was more help to me than AFI when i had problems. AFI tech talked a good story on the phone but i jad to call and remind them 3-4 times. They never have solved my issues and claim it's normal now

 

Bill Hamilton lives not far from me and I visited him a couple years ago when in his neck of the woods. Showed me his shop and projects. Straight up guy. He's mostly into IH stuff but his products are used in different rigs. As I recall, he even bought a 3B with an Fhead so that he could develop a system for it.

 

I was leaning AFI...but Tim is pretty convincing about HFI...I think I'll draft an identical inquiry email to both companies and see what kind of response I get.

At least that will tell me something about the desire to make a sale and willingness to discuss options with a potential customer.

 

Let us know what happen with both quotes

 

Funny you should ask. I already received an answer from Bill Hamilton within about 2 hours of sending and we exchanged two emails fairly rapidly after that. He was extremely responsive to my questions. I have not heard back yet from Affordable, I even checked my spam and trash folders to make sure.

Hasn't been 24 hours yet though. I'll post an update later.

 

Norm from Afi, first email it took 5 day to answer, and after that we exchange couple of email during one day. Maybe he didn't rush is answer because i said in the first email that i bought a used kit from another person.

 

Unless you have the expertise to program the computer yourself, you are putting all your faith in the company that you purchase the injection from to do it right. I wish I had this expertise or knew someone who did, but alas, I do not. When installing injection on my Jeep about seven months ago I spoke with both Affordable and Howell. I liked Affordable's price as well as the fact that their system also controls your ignition timing, whereas Howell's does not. After speaking with both on the phone, I was much more confident in Howell's ability to set up the computer for my specific engine specs. At the time, Affordable said their shop was changing locations and it would take about a month to get the injection shipped. Other than the fact that my Howell was delivered with a faulty TPS, I've been exceptionally happy. I'm of the opinion that their reliable track record justifies the increased cost.

 

Received an email from AFI earlier...so a little around 27 hour turn time, that is acceptable as far as I'm concerned for an enquiry. Most, but not all, of my questions were answered. The email itself has a confidentiality provision so I can't just copy and paste it, I'm used to seeing that when I converse with an attorney, but not a company offering a service. Not saying its bad either way...it just is.

I don't know anything about the size of either company and if that plays into how quickly either one can turn a sale...or how many each has already sold which could speak to how one seems to have more comments online than the other. But the emails "felt" different...you can't judge tone in an email, but the words that are chosen and the detail of a response says a lot to me. At this point I think the pendulum has swung to Hamilton. I am a novice to TBI and although it doesn't seem overly complicated I get the feeling that Hamilton is more responsive with technical questions as shown by Bill sending a link on how I can convert my own distributor to work with EFI if I wanted to...without me even committing to a purchase. His stated turn time is approximately 4 weeks, we'll see. The $1,400 price is my limit right now so other companies that are higher are out of the question for now.
