Has anyone here used the M-Tuned fuel rail with the Techno Toy Tuning adapter?

Going to throw this out there.

I used this product to keep the big chunks and water out of my Honda filters.

I wonder how much filtering those booties provide? I just did a fit check on my NB T3 plate and I'd have to ditch the a/c to use the filter socks. I'm hoping the a/c line can be bent far enough to get the stacks on.

They are selling it under the circle track racing products category. It is a very fine mesh material. I would liken it to a nylon stocking, but much heavier, does not stretch and more durable. I don't know if that helps.

Thanks for the note on the AC lines. I am putting mine on a NA.

sv650_ck

The AC lines are easily bent. I've got enough room now to add the uni-filters that came with the kit. Pretty much done with the install - very simple/quick install. Only had to fab a bracket for the throttle cable. Started right up after opening the butterflies slightly and reducing the idle fuel by 50% (pulls a lot less vacuum).

What are you using to hold the cable stop on the end of the smaller diameter pulley?

I was messing with mine today, I have 100% throttle actuation, but that cable stop wont stay put. I was thinking of slotting the outer edge? The tension will keep it there no problem, I think... Just needs something to stop it from sliding up. Would suck to be driving and have the throttle cable slip haha.

I drilled a 1/16" hole just above the cable and safety tied some wire to keep the cable from coming off the pulley.

Have you fired it up?

1vicissitude

Ah I was thinking about that too. Needa quit being lazy and get back to work.

it started right up - only had to open the butterflies a tad to get it to idle @900rpm. Still need to get the filters oiled up and carbs synched before trying to road tune.

Anyone thinking of using the T3 adapter in a RHD MX-5/Roadster? I would re-consider!

Us aussies have been running into all sorts of issues, first thing is that the 4th velocity stack hits the clutch master-cylinder hardline and there is no simple way to fix this. There's not enough room to even bend the hardline out of the way. The second problem so far is that the brake proportioning valve has to be relocated as it significantly obstructs airflow to the 4th throttle body.

To fix the clutch master cylinder issue, a couple of guys on mx5cartalk have figured that we could machine a flat surface on the master cylinder and use a banjo fitting with braided line instead. I've sent my master cylinder to the machine shop and they will be cutting down the master cylinder outlet and machining a flat surface for the banjo, the thread depth will be increased accordingly too.

I will relocate the prop valve into the wiper cowl area I think.

UK based, so very interested in RHD solutions!
Please post pics when you have it fitted.

Wouldn't that be a problem for any itb setup on a rhd car? Couldn't you use a shorter velocity stack?

OH sorry! I meant the TPS is hitting the clutch line, but the brake proportioning valve still obstructs the 4th cylinder velocity stack. Could do a shorter stack but relocating the brake prop valve is fairly simple anyway.

Finally finished it up. It's driveable but definitely needs to be tuned. The flow meter is from JCW and worked really well for synching up the itbs.

Edit - Speed density tuning wasn't cutting it. Quinn was nice enough to send me his Alpha-N map which I pulled his fueling and timing from and it was good enough to get it running. A couple of hours of road/self tuning and it's actually running really well. Lots of untuned cells but it's a good starting point for NB's using the stock fuel system.

Ran into a little snafu with a stuck throttle. One of the inner filters came apart and held the throttle plates open. Brakes don't work too well without a vacuum. Wrong application for the Uni-Filters??

I've since gone to the booties that Depulse posted. Really good quality and seems to flow much better than the filters.

Thanks mate!

Have you sorted out your vacuum feed to brake booster? And hows your current tune going?

Your welcome. Brake booster is tied into the vacuum block. Brake feel/power is oem like. Very satisfied with the TPS only tune. Very streetable.

Nice!

Are you using any IACV? Would love to know how it does with AC/Headlights if you're not using IACV.

The Adaptronic has an idle control option using ignition timing. It works fairly well but an IACV would be better. No load idle is set to ~1050rpm. Headlights on high doesn't affect the idle but add a/c on high and it drops down to 800 or so.

Thanks mate. Gives me a bit more confidence when I get mine setup, can't wait!

sv650_ck can I ask you for a small favour the next time your in the engine bay can you measure the length in cm from the inlet at the head to the end of the velocity stack please. I gave up on my old t3 setup due to time on getting the pulley sorted and not having time to mod the inner one to give an oem fit so going diy for the new setup but need to work out max length I can get away with

Sure thing. For an NB, it's ~22cm from the adapter plate to head mating surface to the end of the T3 stack.

thanks dude that helps plenty looks like I can get a good amount of induction length

Speed Junkie

Kind of a random request but I don't think it deserves a thread of it's own.

Does anyone know the distance between the threaded holes where the stacks mount to on the TBs (for the AE101s if they happen to be different)? Also, if someone would happen to know/could measure the distance between the center of each runner on the TBs would be awesome! I know that this would me limited in terms of accuracy but all I need is a rough estimate. I'm designing some stacks in my drafting class so I need to know how much space I have available between stacks (at the lip.)

I would really appreciate this information and would measure these myself if I had them in front of me

BTW, I had a chance to checkout a factory Mazdaspeed ITB kit.
http://www.mx5cartalk.com/forum/view...p?f=44&t=38550

It's in a mate's car.

Anyway... quickly checked out the throttle pulley and it's using a unmodified pulley, uses the larger one and not the smaller one like most are doing now. The throttle cable is the standard NA8 cable. It seemed to open all the way too.
