You better pray your wife doesn't find out you could have gotten an equivalent/better ECU and spent $1100 less.

So tell me, for us folks with a Hydra that are considering switching to MS3.. Can you use the same wideband and knock sensor?

You can use any wideband you want with MS3 as far as i know... as long as you can get the correct offset curve on there.

Or you could sell your hideously expensive Hydra-specific wideband and use the money to get a brand new MTX-L and a 12 pack of your favorite brew.

I would ASSume the knock sensor could carry over, but i was also under the impression that Hydra used the stock knock sensor. Is that not so?

The Hydra wideband can't be used, because its only a sensor, and you also need a controller to control the sensor itself. So sell the wideband to someone else with a Hydra and get an AEM or an Innovate.

The knock sensor can be used with the MS3.

Oops, sorry. Thanks for straightening me out, Rev.

Exactly. Just to add to this, I would personally recommend the NGK Powerdex AFX which would allow you to still run the same sensor (and it comes with a new sensor when you buy the unit too) IF you modify the connector back to stock.

CONN-85590 for pigtail or CONN-00135 for kit:
Home » Shop » Wideband O2 » O2 Connectors » 8 way NGK / NTK Connector Kit to adapt Bosch LSU Sensor for NGK Powerdex AFX

Do you want to know why I think the AFX is an awesome choice in order to save $40-60 in order to hold on to a spare sensor for the next 5-10 years!!!???


please say yes.

when the purple text comes out, all hell breaks loose

Brain, I was about to say, check this IP to see if its Techsalvager's but then I realized it was B motorsports.

I like the NTK wideband, I hate the fact that they're morons and refuse to make it with a 52mm round gauge.

Um, not in that font no. The Powerdex is made by ECM who makes the pro units used in calibration and designs for many OEMs. It is very good for reasons I could go on about for a long time.

The AEM units have gotten better over the years and are presently a solid choice. The innovate systems have gotten better over the years though I still have a few issues with some of their products. I have personally used several controllers from AEM and Innovate and ECM product and the Powerdex.

For any application under $1500 (when you start to step into the AFM range) I currently recommend the Powerdex AFX. The exception is when you need some of the features of the AEM or Innovate that the Powerdex doesn't have.

As a side note and perhaps what Brain is alluding to is that my company does sell the AFX. I also sell the AEM and previously sold the Innovate units (we stopped because of problems with the product). Having experience with all three and presently selling two of them, I recommend the AFX based on price/quality and in reference to this thread because he can re-use his sensor. In reference to the $35, the NTK sensors cost more than this and are generally regarded as better sensors. In regards to the connector, just pointing out what can be done. I'm not here to cull profit for a connector sale, just trying to help because I have a Turbo Miata myself and follow this forum (one of the better ones I have used over the years). Same reason I created a Miata specific connector page and will be working on that for the community. Because track enthusiast with same car. Not because $$$. Miata parts sales aren't likely to put a dent in anything either way so just here to add to thread.

you guys are making it too hard.


here's the top 12 reasons Brain thinks you should buy a AFX:

1. Has a big bukly sqaure box display that is impossible to mount anywhere, doesn't refresh fast enough, and washes out in direct sunlight.
2. Only reads between 9.0:1-16.0:1 (1) AFR so has 43% less resolution than most competetors; LC-1 is 7.35:1-23.4:1.(2)
3. Unconventional so you get no support from the community.
4. 13' (3) feet of wiring so you can use the excess to make a friendship bracelet for your BFF.
5. If you do cut the wiring harness to make it a reasonable length, and make a bracelet for your BFF with the leftover, you'll screw up the calibration of the unit (4).
6. Suggested you calibrate the sensor once a week and once a month at most. (5)
7. The wiring for the heater and sensor grounds (brown wire) make little sense (6)
8. It only has 1 output that's not programmable. (7)
9. Takes 1 minute to warmup (8) before working; the LC-1 takes about 25sec (9).
10. Cannot datalog on it's own without another device to capture the output signal. (10)
11. Was the worst sensor in the Ford Muscle Magazine WB shootout: Universal Digital Tuning Products and Tuning Tools from Innovate Motorsports (11)
12. You'll impress Techsalvager--it's his WBo2 of choice. (12)

:laugh: ordering one now

I always wanted to make a bracelet with a friend.

Now I just need a friend :cry:

Just for a cost prospective, I spent about $275 to build my MS1 back in 2007. Then in 2010 spent $200 on the MS3 daughter board, then another $90 on the expansion board when it was released. In 2012 I spent $85 on the knock module. So I have had some upgrade costs along the way to go from an MS1 to MS3X, but even all together build costs have been less then 1 hydra update cost.

That's because MS is clearly inferior. I mean it has a manual. Its obviously too simple.

I really like it when I have to scroll through my tables cause they wont fit on a single screen

I used to have to do that with the early adaptronic WARI software


boy do I not miss that :laugh:

Your laptop doesn't have a 27" screen?

You poor poor peasant.
