I stand behind every product I put out. You're the first unsatisfied customer I've ever had. You must have some other motive. Otherwise you wouldn't have ignored my offer to replace or refund at your choice.
Check this guys public profile. He just joined today. He's probably hoping to receive some business and it sounds like he came here to defend poor workmanship. I was thinking about watching the outcome of this situation and if it turned out good finding out where it was purchased and maybe getting one of them myself, but no longer after seeing the attitude he has taken simply because the man ask for the opinion of other.

I never looked at EFIEs before seeing this string. The basic idea is a good one, causing the engine to run leaner by altering the O2 sensor signal.

I know that the manufacturer states that it will not improve mileage without other engine mods, but leaning out an engine always increases efficiency, in two ways: More air is brough into the engine at a constant fuleing rate, lowering vacuum/throttle losses; and excess oxygen improves combustion efficiency, releasing heat that is otherwise locked up in exhaust CO, HC and H2 from a stoichiometric A/F mix. (It comes at the expense of NOx emissions, however. Three way catalysts need HC and CO to reduce NOx.)

You guys should stop feuding, the guy is making a worthwhile product nobody else does.

Like Mike

Now, should I respond to this like Mike did?

Final word

I've said all I have to say.

If you send in the unit, I will refund the $45 plus the shipping cost you originally paid.

actually, what he is offering is better than the usual. usually you will get your money back less shipping so you would be out the $5 for shipping (just a guess). not sure why he thought you had some sort of hidden agenda. maybe he just had a bad day or got a bug up his tail about something before hand.

if it were me (and its not) I would just heat it, move the regulator and be on my merry way. it is faster, cheaper, and gets your project moving.

if you don't plan on doing any more business with that company then cut your ties. we are all fairly intelegent people so do what you have to do to get your moneys worth out of the part and buy elsewhere when the time comes.

if these devices work the way they claim and there is enough benefit from them then I am sure there are other places to get them. not knocking you big mike but first impressions tend to linger. in a world of chinese manufactured crap, I personally care about quality.

BTW: if there are surface mount parts on the rear of the board, the solder viscosity should keep the parts on there even when melted as long as you don't abruptly move the board. delecate is the key. good luck man.

also in manufacturing, they usually use a glue to hold parts in place until they are sent through the oven. usually there will be a sappy material in the middle of the resistor, usually burgundy colored. that is if this board isn't home made.

There are many people who manufacture these units. Just look on eBay. Or do a Google search.

skill isn't always the only factor here. principle to me is even bigger. If I buy a part that will save me time (and time is money) and the workmanship is crap. I am going to say something about it.

and no, this isn't my fight either.

also the concept of the EFIE is pretty simple, you are simply inputting a voltage on the oxy sensor to make the input to the computer think that it is running too rich so it leans out the mixture even more. you can do this with a D cell battery and a potentiometer. why not do it that way then? because it takes time and my time is valuable. it is much more cost effective to get someone else to do the leg work and pay them a couple of buck so I have more time to spend with my family and doing the things that I enjoy. also it takes time to figure out the limits and wether or not you are running too lean and could possibly damage your engine. which we are ASSUMING that the seller of this product did. I personally don't have one of these and don't plan to because I would be putting my trust and the longevity of my engine in someone elses hands. like you said before....not my fight.
