So I've been piecing together my turbo kit and I'm at the, oh no, I also need an AFR sensor to tune my chip, point. I work at a parts store, and after hours of digging, I've found a wideband 5 wire that I can get for 45 dollars. That, and a diy controller, and possibly a diy display, or laptop printout [I'm still at the sensor and controller step, I'll figure out the display later]... I like diy. I like learning, I like doing, it's less than 300 dollars, etc.

Has anyone tried this type controller? Can I get away with any wideband sensor, and if not, what are my restrictions? Also, are sensor and bung threads generally universal?

 

Why not just get an innovate mtxl? Its like, 160 on amazon, datalogs, can emulate narrow band signals for stock ecus, etc.

I know youre wanting to do it on your own, but innovate makes some decent, cost effective solutions

Also, that guide is over a decade old. Im not really sure how effective the system would be vs a modern system

 

It pulls a 95 civic vx o2 sensor and I have a 94 del sol. No bueno?

 

these guys have what you looking for

just dont get caught up in DIY
its like reinventing a wheel.
you can do diy up to a point where you need to add up how many hours you GOING TO spend on it and how much is your time worth

you can buy a wideband kit on ebay for 140 shipped i found few
and you can buy a used kit for 80-100 bucks


if you save 4 dollars on buying a bracket for your ultragauge and then spend 2 hours making one did you really save?

 

Thanks for that link. Are sensors universal? Do they produce tbe same output voltage? Do they have the same threads? If I can get a sensor for 45 dollars, or wait until payday and spend 100 more for the same thing, which should I do?

 

Yes yes and yes. Look in the classifieds for used widebands. Save yourself time and money.

 

You can get Bosch Wideband replacements for $50.18 on eBay. If you go with a AEM UEGO that comes complete it is $157 without looking too hard for a brand new one and it uses the cheaper replacement listed above.

Widebands aren't something you really want to be toying around with being that you NEED them to work to not destroy your engine.

 

I appreciate the helpful replies. Gonna pick up one from advance. I'll post part number for reference later.

Bosch 17014

 

I'm a little bit on the fence on this one. One side of me is saying yes. Go ahead and make your wideband controller. You would a lot about how wideband controllers and how they work. You will also have a strong sense of pride knowing that you made your own wideband controller

But the other side me says that its not worth it. When doing all that soldering you're bound to have something shorted out or something not connected right. This will bring about hours of trouble shooting. And then after you have assembled this unit and everything is working fine then you will have to learn how to tune your car. This also will take time and you don't want an intermittent sensor while your tuning.

But at the end of the day not about the destination its about the ride. We all want a fast car that's fun to drive. But once we have built that fast car, what's more important. Having a fast car or having a fast car you have put together yourself with your own skill and craftsmanship?

 

Valid points, avery. My dad worked electricty in the navy, and I've so far built an ecigarette, modified an xbox wireless reciever to adapt to usb and work on my pc, and socketted my ecu. I think I'll go for it. Wish me luck :]

 

The part number I use is 17018 which is also a Bosch.

 

After reading this guide I would highly suggest not to use this. This is really old information and not really a true wideband.

 

Well when I priced the parts, I decided on an APSX D1 I found with display for about the same price. I may do it one day when I'm really bored, but just for fun.
