Miata ITB running on MAP only.

Miata with ITBs running off of map sensor 100%. No TPS. In speed density using megasquirt. Tuned by Horsepower logic.

That is a smooth idle on an ITB setup!

Why is the starter of a miata so satisfying to hear

[chanmanthegreat]

I want to go with ITBs on my NB so badly, there is something so special to me about a reliable naturally aspirated clean engine bay that sounds amazing. Im just worried I might regret not going turbo for more power later on down the line...

[sugoi]

Do you have more info / videos on this build? I'd love to know more about the motor

[Fred_the_]

how did you get it to work without a throttle position sensor? did you just tune it as if it were always at wide open throttle??? or did you use vacuum to guesstimate the rough throttle position?

[SuperWepawepa]

Im running the same OBX itbs!!! But im using dual maps. One for Speed density and another for aTps fueling. What other mods you have?

[nathchp]

Does this use stock injectors with a mega squirt, and what changes to the throttle cable?

[MrTAKIS]

Can it run properly with stock ecu?? Sorry for my english

[xzmjode]

So with ITB do you need a air filter. How does debris not go into the engine?

[LeanLauri]

How did you connect to the map sensor?

[hasdh]

I'm guessing that megasquirt is also getting the RPM as input using a crank position sensor? how would it otherwise be able to calculate the Mass air flow...

[michaelovitch]

Are the 4 vacuum ports linked to a vacuum tank ?

[SU]

No vacuum line connected to the fuel pressure regulator? Cause I am about to setup mine.

[rileyjohnson]

Should have talked chris into doing itbs😂

[Nasonix]

Which flywheel is it running? The revs are definitely a little faster than mine which is turbo with stock flywheel

[Lukewilson]

What happened to the oil gauge as you revved the car, dont look right.

[mother_herd]

Can you run a itb on a daily driver miata with a stock engine bay
just curious

[arthurrietveld]

Wow, how did you make the the map signal smooth? I see you fuel pressure regulator is not connected?

[MiseryPhD]

Questions.

What kind of breath filter is that

I heard it's actually not healthy for the engine?


After you got this ITB conversion, what kind of tuning did you do?

DId you take out the engine or could install it like that?


Looks amazing!!

[Flaco]

I can reprogram my ecu to deleted the flowmeter?
