Here is my objectives:
Running 8 PSi on a stock internals b18b with a TD04HL blower and 2G talon Intercooler

Here is my question.
I am pretty much new to turbos but wishing to learn more. I got my tubo and I am in the process of choosing a fuel management system for my project. As what I've heard, I came to 2 choices. One, would be buying a ECG SMC , 4 X 450 injectors a resistor box (200$Us...) or get myself a Vortech FMU 12:1. I don't need much of tuning, everyday driving car and willing to pay minimum but still having good and reliable car. Please give me the pro and cons...

Btw... If I use a 12:1 FMU... how would the OEM honda b18b MAP read the boost? Would it trigger my check engine or would it cause any other problems?

Thanks

no one here to help me ?? sorry.. abit newbie on that subject...

To keep the MAP from reading boost you would need check valves or a Missing Link.

I'm in a very similar position - I've got a stock B18b1 running 7psi with a 12:1 FMU. I got the FMU and inline fuel pump (which you WILL need with an FMU) for a good price, and at the time I wasn't too sure about the SMC, but at this point, I think it's pretty much proven itself, and for the price, with for a low boost application, you can't beat it. Wow, that was a long sentance...

I had too many issues with the SMC. I would go with the Vortec FMU!

PM me with the issues please. I'm curious.

I know guys have had good success with the SMC but I will give you a real world experience from an unbiased source. I also post on ClubSi and the bias seems to be toward supported products so, I will tell you my experience with this product.
It is not a pretty product that you will want to show your friends. When I used it I noticed that at certain RPMs It would make the car jerk like taking out the clutch too quick. It did not make better horse power on the dyno and I could not get rid of the CEL light.

It was not a product I would recommend. Hope you have better luck!

you have to remember that it is now upgraded to the SMC+. Twice as much adjustability. The reason for the jerk we a sudden over irch problem in the 2 dial (rpm range) of the origanal SMC. Anyone with reviews on it?

Understand that with the FMU you will need:

1) A high pressure fuel pump. Airtex & MSD inline work fine. Walbro intank WILL NOT DO IT.

2) Missing link / check valves.

So because I dont have this, does this mean that im leaning out?? I had my car dyno tuned and it is perfectly fine...I do have a 225lph in tank..I know that it does not flow 255lph at our fuel pressures but what exactly will not runnin one do??

Well I ahve heard of a lot more bad stories with the FMU's than with the smc+. The new SMC+ is a big advance over the previous one in clearing up those issues mentioned. From what I hear if you have the old SMC and want to upgrade it, the guy does the upgrade for relatively cheap. I may be completely wrong but I believe it was something like $10 plus hipping for the upgrade. I would (and am going to) go with the smc. FMU's have a tendency to lean out sometimes and what not. Injectors just aren't meant to run at near 100% duty cycle.

How do you "dyno tune" an FMU setup? There is nothing to tune.

Don't use a Walbro intank with a 12:1 FMU. It CANNOT create enough fuel pressure:
