"Honey Badger" Miata: Turbo Track Build (new brakes installed)

[TurboTagTeam]

I just installed my AEM wideband. One of my favorite mods yet.

I am more concerned with the exhaust at the moment because the AF ratios should be fine...at least they are for every other MSM with the same mods.

Ah yes, the same mod assumption.

One thing you will learn quickly, and hopefully not the hard way, is that EVERY turbo car is different. Same mods or not. This is why mail order tuning is not the best option, and why you NEED wideband.

You were having a problem getting "cut" earlier, sounds suspiciously like detonation. Detonation is not good. Get a wideband and something to control your fuel.

It was cutting before because my boost was set too high, so I was told by the company that sold me the intake kit.

Im confused. They owned the car previously?

If the boost was set too high then what Im saying is correct.
You cant add more air without adding more fuel or you will have problems. These mods all free up air throwing your whole ratio off. You need to see what is going on in your car to get your money's worth and to keep your motor happy.

They didnt own the car, but they said that if I was getting the cut after installing everything in that intake kit, it meant I had the boost set too high, so I just tuned it down.

If being cautious to the tune of $200 bucks or so for a wideband set up isn't worth it... maybe a $5000 engine rebuild will worth it to him.....

You should talk to Chelsea. This Miata made more torque than horsepower on an EBAY turbo kit that lasted many seasons.

Yea, you read my mind on that one

Agreed....hands down the wisest investment i did to my dsm.

[CleanNeon98]

How do I go about reading the gauge when its installed....or what do I even need it for?? Dont know about widebands

[Spoolin_VQ30DE]

just got a Zeintronx wideband... i found this when trying to figure out widebands hope it helps

LULZ.... read what you wrote again.



Its a gauge.... you connect it to a sensor.... and read it.



In all seriousness though... it tells you what your afr is at any given second. Some even have warning lights that will alert your attention if things get hairy. Its basically a gauge wired to a control unit, which is then wired to what appears at first glance to be an O2 sensor. But a 'wideband' 02 sensor works at a different voltage, giving you a wider, more responsive range of readings.

For example... on Subarus, i look for about 11.5:1 afrs when i'm spooling up and making torque... Then it tapers down to about 11:1 as I hit redline. Turbocharged cars normally require a little extra fuel at the top end. Not because its needed for spark, but because its needed to cool the cylinders to prevent detonation.

Wideband tells you if your car is going to explode or not.
Find the desired/recommended ratio (mixture between air and fuel) and if it deviates too far from that stop driving. If you have one of these you can get a fuel controller and tune yourself (Dont Use and SAFC unless you like your timing to be more retarded than... a really retarded person)

If you are replacing the DP might as well install wideband same time so you can get the bung welded in before pipe is installed.

In all seriousness, I suggest you read some more before you mess something up.

lol, I tried not to... good info tho.

[JET02WRX]

Heres a visual example of how a wideband helps you tune... This is from when I first installed my 16g. I was working on an issue where i was getting odd readings richer early on, then leaner than what my fuel table called for.... I would have NEVER known the severity until I had wideband, because the stock 02 sensor peaks at about 11.5:1

The stock boost/fuel cut is set at 10 psi. Detonation with the basic bolt ons won't occur until 11.5-12 psi with 93 octane, stock IC, warmer weather.

What if I do the 2.5 exhaust and then get a larger intercooler, do I have anything to worry bout?

[i like rice]

No, because you'll hit the fuel/timing cut before you hit detonation unless you bypass it or go with a standalone or piggyback ECU.

It'll also depend on which downpipe you go with. From what I've seen, the split gas design has been more prone to boost spikes.

I'm running the Flyin Miata DP and with the PRofec B, I see spikes of barely .5 psi in 5th and 6th gear. It'll hit 10 psi for a split second then hold steady at 9.5 psi.

So if I get the FM exhaust (DP and exhaust) and a larger ebay intercooler, and turn my MBC to 9-10psi, will I be ok?? Dont need to change injectors?
