Just a little history; I installed my greddy kit last year and was running the storied "severed-injector mod" for quite some time. Problem was, the throttle tip in/out was so unpredicable that you could not carry a line in a corner at anything but full throttle or coasting. This behavior (and other annoyances) became so unbearable after DGRR'07 that immediately after returning from NC/TN I bought the Int-x.

Unfortunately, the Int-x, and the RX8 sat basically unused, the int-x in it's shipping box and the RX8 in the garage, for the entire summer '07 because of work. Around November, I decided to schedule a dyno run at an open house in Sterling VA (Mach V) just to get my butt in gear and work on the car. I should have known I would wait till the last minute to install.

So on a Thursday night, I pull the car in the garage and the install goes smoothly. The hardest part was yanking the emanage harness back through the firewall. I shut the hood and the car fired right up. I tentatively drove the car around the block, keeping one eye on the boost gauge and one on the AFRs. No issues. I shut down for the night and fired the car back up on Friday evening. I puttered around for a few minutes and finally said "**** it" and opened it up.

Wow.

Pure, smooth power. Smooth easy transitons into boost. Right out of the box, exactly what I was looking for.

The next day, we strapped the car on a dynojet and did two 5th gear pulls. No problems. Graphs are posted. Note that the AFRs are tailpipe readings. My wbo2 never got above 11.9. Also the graph with rpm on the x-axis end early due to breakup of the inductive pickup.

250 rwhp at 8 psi two days after installing the int-x aint bad.

Hears to 300.

 

Wow, congrats! I bought the int-x last week and cant wait to install it.

Before you added the int-x did you do the Step1 and Step2 mods listed by MazdaManiac? or just Step3?

 

Were you still on the blue e-manage?
How much boost are you running?

How do you plan to deal with Maryland emissions?

 

If you are refering to the problems that MM outlined in the "Definitive Fixes" thread, and I remember them correctly (and I just looked), I did 2 and 3. I did nothing that I recall for the air pump, though I didn't ever have a problem with it running at odd times. It is possble that I did do a fix and dont recall. For 2, I drilled a hole and installed a nipple on the turbo out. This was not necessarily to fix problem two but to get a good signal for my E01 boost controller (which in fact was the essence to problem #2, I guess.) The fix to problem #3 was absolutely elegant and straightforward. I am forever in MadDog and MM's debt.

 

Yes
8psi maybe 8.5. If it warms before I stash the car, I might try 10psi, but it is likely the car is going up on jacks for more "renovations" for the winter.

Carefully.

I have three options.

No boost for 20 miles and three ignition cycles. This would also require me finding a cat. rkostolni still has my stock cat. This is the most likely possibility.

"Move" to Talbot county. No emmissions there. A friend who lives there has offered his residence for me to register my cars. This seems difficult, annoying and illegal. Not that any of that bothers me.

Get a law passed to eliminate emissions in MD. This seems vaguely unlikely.

 

Glad to hear of your out of the box success Carbon! This is actually very typical results with the base map on the Interceptor-X. If you need any help we are just a phone call away, Scott

 

I had similar - 250 whp seems to be out of the box for the default map. You really should get it tuned though. It feels a lot stronger and you'll get 20 or more whp.

 

Last time I did emissions in MD, it was just the typical OBD-II test. No sniffer.
If you car is like mine, it won't care about the CAT and won't throw a CEL if you leave it deleted.
However, I got out of it by being "too low".
The guy running the test looked at me, took my $14 and said "You are too low for the treadmill. See you in two years." and that was the end of that.

 

Don't expect that luck here. The emission devils here would say "screw it" and just drive you car up onto the rolls anyways, scrapping it the whole way and laughing.

 

I don't doubt it.
But, where Carbon lives, he might be able to get away with it.
The emissions facility near my house looks pretty modern (and my car will pass since it has the EMU and not the Int-X).

 

I would have to get lower (which would be...just...silly).

I might have lost an inch with the FLT's (and replaced the nose with an MS, which is a good half inch lower than the stock with the app pk.), but they still got it over the humps. Barely.

I have until next Oct to come up with a solution. So that means I might start thinking about what to do in ... November.

 

I managed to get over a year of extensions out of them before I finally had to send my plates back to Maryland.

 

 

There is ALWAYS a shady shop around who will pass u with barely stepping foot in ur car. Talk around, get a "referral" from a friend or someone in the know and pay an extra $25-$30 to get it passed. Took me 2 days to find a shop that would do this here in TX. I just go and slap another $30 in the guys hand, he pulls the car in the garage, puts the stickers on my windshield, pulls it out and im on my way...5 minutes max. These shops are dime a dozen.

 

In Maryland (and Phoenix) they don't use "shops" like they do in Cali and elsewhere.
The Emissions Inspection Stations are run by da Gubmint. They are purpose-built facilities.
