I suggest trying to get the wideband installed and working before doing the injectors, for two reasons. A) the lc-1 is finicky to install for some people (me included) and you will definitely want to know that the wideband is working correctly before putting in bigger injectors.
and B) the wideband will help you know how well the ecu is set up, and will probably provide information that is vital to you getting your car running well with the new injectors.

as far as installing the injectors go, its a really easy job, read the ms manual about it to get all the ecu requirements, (reqfuel), and its just unbolting the fuel rail and popping in the new injectors and wiring them.

good luck,
Evan

 

This x 1000. You're being pretty cool. So i wont make fun of your car as much any more. What your looking for here you will find as far as turbo's whether you want 200 or 500 hp. You have taken a correct step in megasquirting your car first off. I was able to get mine kind of peppy with the megasquirt. But... there is no replacement for a magical turbo.

 

Just downloaded it now, is it really that easy though! I hope so, I'll mess around with it at the weekend. Thanks

I'm here for the info! and so far, from all the reading I'v done I think I've learnt a hell of alot about miata turbos!
I'm not interested in 500, more like a subtle 200 would do me

Yep Megasquirt was a must, I had toyed with the idea of a bipes and fmu, but I thought If I'm going to do it, I may as well do it right!

I'll fit the wideband tomorrow and see how I get on, and then possible get the injectors in by the weekend.
As far as fitting the wideband, would the cat be a suitable place for it, obviously there's no core in the cat
It would be an easy place to stick it, as its only four bolts holding it in!

 

tuning fuel can be, if you pay for the extended version. There's still more than tuning a fuel map that these n00bs don't understand

 

^True.

Do buy the extended version. You'll be able to easily get a safe tune.

 

Okay, just bought it, well I gave them money, hopefully I'll get something in return!! Is there a download link in the email I'm waiting on?

To tell you the truth, all I want is a safe map, I'm not actually interested in getting huge power at the moment, I've other issues to sort before I go for that.

As long as the cars not going to blow up the minute I see some boost then I'll be happy enough!

 

should just need to enter the registration code into the software.

 

Yeah thanks, just got it after I posted, all done now, I'l fit the wideband tomorrow, will it be okay in the cat?

 

Check this thread out. I'll be running mine up through the engine bay and through the firewall though.

cool people position the sensor just in front of the cat, then they put the controller behind the radio and bring the sensor down under the shift boot.

 

Meh. I'd rather put it in an A-pillar pod and keep my air vents

 

Now that I think about it, I am pretty cool, I mean I do drive a soft top, in Ireland, you'd have to be cool to do that!

Air vents Don't bother me, I'l keep the two on either side, the ones in the centre console can be donated to a greater cause!

 

One for all the haters of my little car, some snaps from a recent feature.






Got a little bit done on the build, welded the bung into the exhaust, after a look at the possible locations for it, I ended up putting it into the neck of the cat.
Going to dive into the dreaded wiring!UUHHHH, just having a look at a few build threads to see how to do it!

 

your wheels are broken.

 

Yes they seem to be alright!!

 

they seem to look stupid too.

 

Cuts deep

 

Where's the lemon juice? Or room 101.

 

Got the wideband in yesterday, oh god was that a horrible job. I don't have the patients for wiring!

But its now up and running all the same. Although I'm not too sure of the accuracy, the gauge and megatune are reading differently. And as far as the gauge is concerned, the car is overfueling abit.

This is all on the Megasquirt base map, so abit of fiddling will be needed to see what the story is with it!

And a quick question for someone in the know, for programming the lc-1 into the ecu, what is the volt output from the lc for 14.7?

 

Hope you used the same power and ground for the ecu, LC1 is finicky like that.
