Advice for exhaust and FI unit

[cornell]

What's up everyone ….

I've been a lurker since June and a M50 owner since October. I've
used this forum for much research and "how to" and don't know what I
would do without it.

I'm purchasing the JARDINE 2-2 EXHAUST but still deciding if I should
get a FI unit since my girl friend is willing to buy one for my
birthday in august along with an intake of my choice.

I would like to hold off on the FI unit and let my GF purchase it, since my budget is real tight and plenty of BILLS because I recently purchased a place. If I go without an FI unit would I suffer in drastic performance or can I hold out until august?

What do you guys think and what would you do?

A: buy the exhaust and wait until august for the FI unit

B: stop being a cheap, live a little and get the exhaust and FI unit together.

All your advice is appreciated…. thanks

I'm ordering an exhaust on Monday and won't have the money for A power commander III for another month. I'm not worried about it cause during this time of the year I only get to ride a few times a month. I wouldn't want to ride it everyday without the FI unit and new pipes though.

You might want to talk to QuacktheDuck, he is thinking about selling his jardine 2:2 and getting the 2:1 setup.

How about buy the exhaust and see how it runs without the FI? Since the FI and intake will be coming from your girlfriend (I like her!!) in August, it's concievable that the bike will run okay with just the pipes until then. If you lose torque or the bike starts backfiring and the pipes start blueing under the heat shield, I'd go ahead and get the FI early, and let your GF buy just the intake, since that's an expensive purchase by itself anyway. You'll find this all out within just a few rides I think.

Hey cornell, welcome to the boards. i just sent a reply to your pm about the pipes.

I am hoping the Jardine 2:1 will run ok for a while without a new processor.

Be sure to post the results when you get them installed. That unopened box in my garage containing the Jardine's 2-1 Megaphone's keeps calling out to me "try me".

Will do.

Survey says...."ERRRRRRRNNNTTT". Let the g/f buy all the goodies for you, store them and put them all on together at one time. Skip the Fi2000 unit. With the air intake and pipes you're going to need the Power Commander III.

Don't make wholesale changes w/o the proper ingredients.

I would get the intake, exhaust and fuel controller and install them at the same time.

[bassmaster]

Me too. that's why mine hasn't been done yet! Waiting to get everything at once as well as waiting for $$$$ which always seems to be the case!

Seems to me that a lot of you guys are forgetting that the stock EFI unit on the bike can be remapped by the dealer. Might not be perfect, like you can get from a PC3, but certainly good enough to keep from doing any damage till you can get an aftermarket unit.

Local Dealers charge $90.00 an hour for labor.

My stealer will do this for $60, but says it is really only good if you are only doing aftermarket exhaust. He said if you also get an intake the stock ecu can only be remapped so far and with intake and exhaust it will still run lean.

When you put an aftermarket ECU in your bike, the stock unit stays in place. The stock unit is still controling your fuel / air mixture, it's just getting different signals from the aftermarket unit. Your dealer is wrong, ask him why you can lie to the stock unit to make it work, but you can't program it to make it work. Your stock ECU is actually a better, more sophisticated fuel processor than any of the aftermarket units. It just all depends on how it's programed. It's possible that your dealer doesn't have a program (MAP) for anything other than pipes, but saying it can't be done is just wrong.

Couldn't tell you, it was the guy who runs the dynojet dyno machine. They are an offical dyno jet center so maybe they say that so you get a powercommander from them.

The dyno shop that I had mine done at said the factory fuel controllers adjustabiliy is limited and the PCIII is fully adjustable. I've said this before, if you are going to spend all that money on intake and pipes why skimp on a fuel controller and map? I want to get the most from my bike. I want it to run right.

I just searched e-bay for the cheapest el-cheapo cobra fi2000 and found an awesome deal on a set of pipes at bikebandit.com and I'm happy I did. The bike runs great. If you want to spend $300 for a power commander to be able to fiddle with everything on a laptop for hours on end for an extra 2hp that you may not even feel anyway then go that way. If I didnt have a budjet that is the way I would go its definetly the better product. But unfortunately I have to watch what I spend. And I am very happy with the Cobra.

Just try the pipes first. You may want to have a FI processor on order, or already on hand becasue you will probably end up needing it anyway. Some bikes need it some don't. Mine ran like crap after installing the pipes but I had already ordered the fi2000 and had it ready to install.

Just buy everything a piece at a time, that is what I did. I did a bunch of research on what I wanted and made sure I got the best deals on the parts I wanted to have.

I have added the Jardine 2:2 and thunder MFG air cleaner but yet to install the Techlusion unit, the bike runs fine but a you feel it being hesitant on the first 1/4 twist of the throttle. This is where you need a FI unit.

[BillyBumbler]

Toolboy, try this: In 4th or 5th gear, cruising at around 40 mph give or take, grab a handful of throttle like you mean it. What happens? What should happen without the TFI is that the bike will not get that gratifying instant surge of speed and torque. That's the biggest difference I notice.
