hey guys, looking to buy a new miata, 2001 5 speed.

Im in NC we have a OBD-II inspection here meaning they have to hook up to the port.

are there any plug and play turbo options, or ones that are very simple to tune with a piggy back. i'd like to make around 250 whp. I was looking at the ess supercharger kit, but it looks like it will only net me about 200 whp.

I have read that running MS parrallel with the OEM OBDII will work. Can someone explain to me how that works. will it pass inspection all the time like this, or will it require making changes every year to get it to pass?

wow your post is exactly like mine....

did you find your answers? where?

brianfulcher15

haha no... nothing but search you a hole comments and it cna be done but no links to anything beucase were not spoon feeding you... i'll probally just go with the ffs kit anyways its direct bolt on and the turbo kits requres you to cut part of the body to fitht he turbo in.

Are you inebriated. Spoon feeding? I don't call drawing from other experiences spoon feedings. It seems that this discussion is the dirty secret that nobody else is willing to talk about. I think I've found most of my answers though.


The "dumb" programmers use a safe table that most cars will work with to keep the narrowband o2 in check and wont trigger a light unles you're hammering on it so hard that it goes beyond its reading capabilities. I was wondering if you can fully disable codes and errors with something like an xede in parallel/piggyback and keep the full ready state - which is the only thing that matters on obdII here. There is a visual, but nothing like Ca. or Va.

You can't truly control anything without a wbo2 system, and I was wondering if a xede will be able to disable that cel alltogether and put that in ready state too. I'm going for a low psi boost application so I can probalby get away with it using one of the proprietary devices that go with whatever comes in the kit without having to manage wbo2.

The car shouldn't throw codes in the first place. That's how you get rid of the CEL. An Xede or AEM's FIC or anything else wired in parallel or inline or whatever isn't going to change CEL status or any other codes. OBD-II inspections require a happy OEM ECU.

what i was really hoping to find was directions on how to wire in parrallel a hydra so I could run FM II but there doesent seem to really be a step by step guide to do it. only multiple threads of issues people had while trying but no ones seems to have detailed how to actually do it. Although there are some members whom are running parallel with no issues.

Also on newer cars you run into the issues with the CEL becuase you are usually removing a upper cat which alters the O2 readings greatly when you install the turbo manifold. seems that NB miatas dont really have this issue unless they are CA spec ones. non the less we need that OEM ecu working so we have a functional OBDII port

My debate now is am i going with the voodoo 2 requiing more modifications to the body, and the plastic, or am i goign to send the extra cash and get a FFS kit which is plug and play for the ECU, and is also direct bolt on with no modifications other than removing the manifold and relocation of a few things.

its a hard decision, and my concern is that i'll get bored with only 200 hp that hte ffs provides which is pretty much the limit unless you have E85 available in your area. with the voodoo 2 i could upgrade to the fm II when i have completed more research into parallel wireing.

ultimitally with the AEM wideband, and full pillar pod, and other upgrades i'd want with my voodoo kit i'll be at the price of the ffs supercharger, or not far from it.

Im a year away from getting anything anyways becuase my awesome daughter stood up and pushed her hands thoguh a weak spot in my top so there gots a grand i had saved up towards my turbo kit...

I think Y8s might have run an ECU in parallel at one point. If you search at m.net you might have luck searching for TECII parallel install. A parallel install is similar with any aftermarket standalone ECU. The aftermarket ECU controls fuel and spark (and maybe boost control and some other boost specific functions), the factory ECU controls everything else.

I think 250whp is at the ragged edge of the factory AFM. Stephanie at BEGI probably topped out on a piggy.

200whp on this car would be uber fun, I dont see myself getting bored. Its a light vehicle with a short wheel base. Going higher, you're going to need better meat and bits to handle that or it could get dangerous. Keep the power reliable. Complete the picture with balanced brakes, bushings, and heat management. Most of its attributes are in the handling.

My questions are merely in preparation. I'm looking at units like the s/c with TDR which look like its the easy way to get to that power on a bp4w and then leave room for upgrading later after the supporting bits catch up.

I just want the room to play and have a little more fun while being able to avoid the headache of emissions inspection issues on a 1996+ vehicle. It looks like it can be done.

i was looking at the tdr kits, but its my understanding that they wont fit with the oem shock tower brace.

udelslayer

I'm sure there are plenty of aftermarket braces out there though.

brianfulcher15

well the aftermarket ones ive seen are pointless basically cosmetic pieces becuase you can bend them by standing on them. the oem one is the best available IMO.

Apparently, neither of you has read the stickies. One of the reasons no one is helping is because you aren't following the rules. That is, properly written posts. This includes capitalization, proper punctuation and sentence structure. It's all laid out by samnavy in a humorous post here: https://www.miataturbo.net/meet-greet-40/ultimate-noobs-read-first-sticky-35885/

The guys here know more about engine management, forced induction and Miatas than anywhere else on the web. But, if you want assistance, you gotta play by their rules.

That said, this thread: https://www.miataturbo.net/useful-saved-posts-8/how-make-install-your-own-diy-megasquirt-13676/ will tell you all about Megasquirt, and the options for running standalone or parallel.

brianfulcher15

I probally would have read that sticky... if it were in the engine management section instead of the noob section.

udelslayer

MS works for OBD1 people, but I understand OBD2 is out of luck. This sticky was good, but left me with more questions than it answered.
