Hi guys i have a 1990, i've started saving up and now it's time to start buying parts for the first part of my project, my final goal is to have a miata just like they did on MCM but i'm going to buy a MSII DIY kit since my dad can solder all that, for now i'm going to buy the MSII and a wideband and run NA power for some months while i save up for the rest.

Question is, does the DIY kit includes all the sensors and stuff i need to delete the stock AFM? if so, all i need to buy is the kit and a tuning cable, right?

And what about the software to tune, does it come with it?

 

No, you need a IAT sensor to replace the afm, and some place to put it.

It comes with software for tuning, but autotune is extra.

 

Only the IAT? what about MAP sensor, don't i need? i will put a turbo in the future

also, the IAT wich one is it? Sensors for use with the Megasquirt Engine Management System Megasquirt Kits / Assembled Engine Management Systems, Wideband o2 Sensor Systems and tuning products - DIYAutoTune.com
on that page there are more than one type, of those what do i need

 

MAP sensor is onboard. So you dont need one.

Any you can run any IAT sensor you want. GM seems to be the one recommended though

 

No...

so all i need is the ECU and that IAT sensor

is this kit the same as PNP? i just ask because it's cheaper, what's the difference?

 

It doesn't come with a stock harness interface, you have to buy and make a boomslang harness or cut your stock **** up.

 

you're saying that i have to cut mine and solder wire by wire?
if so, it's a dirty job but it's worth the money

 

Buy an old 1.6 ecu and rip the harness connector off the PCB, or do that to yours.

Just don't hack off the ecu connector from the car's harness...

 

I hope that means youre going to buy a DIYPNP kit.

 

******* jesus christ...or just buy the $10 connector.

 

here's some real advice:

buy this: DIYPNP Nippon Denso 76pin Unassembled Kit DIYAutoTune.com

plus this: MSPNP and DIYPNP IAT Sensor Kit - Aluminum Bung DIYAutoTune.com

plus about 6' of vacuum line.

assemble the ECU following these instructions and load the provided basemap: https://www.diyautotune.com/diypnp/a...3-16b6-mt.html

(both are a tad out of date -- you could ask someone that knows what they are talking about for suggestions on what to do differently)

 

but the PNP is too expensive for me, isn't this the same but without the connector?

There's a difference between being frugal and cheap. I'll bet your Dad, who seems to be the one who'll be doing the actual work, will appreciate the DIYPNP kit more.


Maybe you can't afford to do anything.

 

If the DIYPNP is to expensive for you, then honestly you cannot afford to turbo your car.

 

i just asked if it can be done with the DIY kit, it's a simple answer, yes or no, if there is a product available that is half the price and the end result is the same as the other just with a bit more work, why wouldn't i do it? it doesn't bother me solder wire by wire, i'm not made of money
besides, if i told my dad i bought a ECU for more than 400$... well, he would be ******* pissed, even if i buy the 280$ DIY kit i'm going to tell me it only was 100$

i'm going to ask it again, can it be done with non PNP 280$ kit?

 

No it can't.

 

leave my finances to me, i didn't say i was going to turbo it right away, it will take time, besides, the ECU is the most expensive part in the build, the turbo is 200$ the intercooler 70$, wideband 150$, manifold is 250$ the piping, BOV and stuff won't be much more
i know i will need a clutch and radiator but everything in it's time

i just want an awnser about the ECU, the rest leave it up to me-

and yes, the turbo and intercooler are cheap because here in europe almost all cars are turbodiesel so the turbo will most likely come from a BMW 525tds, a 1.7 isuzu engine or anyone that uses the TD04 turbo (loads of engines uses it)
and the IC will come from a Ford mondeo tdci

 

why? what's the difference between it and the PNP kit? from what i read, the only difference is that the PNP has a connector and the other i have to solder the wires to the car's loom

 

I could turbo a miata for cheaper then 98% of the people on this site, including you. It took me 10 years to get to the point of being able to do that. The biggest thing is knowledge, which you do not have. How do I know that, because you are asking questions that are easily answered.

Yes the MS2 kit you asked about will work, but there is a ton of things that make it much harder to build then going with the DIYPNP. With the questions you have asked I know you have not looked at the MegaManual yet. Being able to solder is only a small part of building the MS. Knowing what circuits are needed for the miata is a big part. Do you know what steps to not due because they are not needed?
