Blitz MFC - I\'ve ended up with it!

Should be able to get a Wideband for under £100 if you shop around - but they are an essential tool for tuning - it will tell you so much more than most other gauges

Like this?

Then get a cheap gauge.

Cheapest I can find as a bundle is these (there is also an AEM unit for about £10 more):

You need a wideband controller - the innovate one is good:

Then the wideband sensor itself (Bosch 5 wire) - they are normally about £45
 
With the Innovate - you can use one of it\'s analog outputs to drive a cheapo AFR gauge - result is you get an accurate gauge that actually works.  You can also use a £5 dpm module with full scale of 1.999v - the innovate\'s output is designed to drive these directly
 
This also looks interesting - but don\'t know much about this one...

This is what I have:

Oddly is £40 more for the same product in the performance section lol

Arg. What are you planning on running this on? Nothing other than light mods (exhaust, air filter etc) I hope.. Especially if you are planning on tuning it yourself and have little experience?

It\'s a nice idea, but very old and at best rough tech! The thought of calibrating the fuelling requirements of a car with just three rotary dials (well two for tuning fuel!) -when you think of the time spent logging, comparing and tweaking fuel matrix maps on a standalone, makes me cringe! (especially on an engine so sensitive to knock.)

Also unless the unit comes with a wideband lambda sensor (which i very much doubt) then the little lights warning on the unit warning you about running lean are next to unless when boost tuning. Even more scary if people put their faith in them

Best to save until you can get proper standalone. You can get a harness from Banzai racing with all the sensors you need for fit a common FD3S apexi Power FC into an FC3S for little for around £100-150iirc

Ben - Yes, only light mods. Exhaust and air filter, and slightly upped boost - if you read the other thread I have going atm, you\'ll see why I\'m thinking of using it. Basically instead of an aftermarket ECU, use this with a wideband and AFR gauge (NOT relying on the sensors on the unit).

For such a simple function I think it\'ll be spot on, and the only cost to me will be the Wideband sensor and AFR gauge. It\'s not liking I\'m trying to map something ported, or larger turbo or bigger injectors...!


If you\'d like to contribute to my other thread too (there\'re still plenty of unanswered questions) then go for it!

At the end of the day, the whole Wideband sensor and AFR gauge are a good idea anyway. But even they will have to wait, finances dictate that advertising myself as a PT so potentially I can finally start getting clients comes first. I\'ll just run at 0.4bar boost ish.

Cool, I\'ll try find the other thread, sounds like you\'ve done your research anyway :Thumbs-up

I\'m basically now just trying to work out why I\'m still getting a boost cut at 0.5bar with an R-magic ECU fitted, that should be mapped for upto 0.9 bar or so.
