Hi from the UK

Hi,

I am new to the forum, having just signed up for the starter package today. I am from Chester in the UK and have been playing around with cars mechanically for a few years but really want to have a go at ecu tuning. HPA seems like a good place to start.

The plan is to convert my 190e to efi using a DTA ecu I have from an old c20xe project. However this may be some time off as there is a lot of body work that needs restoring on the merc before I get round to the engine. So in the meantime I have an mx5 to play around with and practice on!

Thanks

Paul

Welcome to HPA Paul! An MX5 is a perfect base to learn on and should set you up well for the challenge of your EFI conversion =)

Hi Paul,

Welcome to HPA. There's tonnes you can do with an MX5 if you want to mess around with EFI on it before starting on the 190e

Taz, Chris, thanks for the welcome!

Hopefully a stock naturally aspirated mx5 should be fairly forgiving for me to learn on! It's a 2002 1.8 so I think I can utilise the existing engine sensors?

I just need to pick up a wideband and then make a harness plug to connect the ecu.

I know it's probably been asked a thousand times before, but when purchasing a wideband is there any make which is preferred? Or any to stay away from?

It really depends on your preference, if there is none what ECU are you likely to be using? Is it going to be a permanent install or temporary?

I was going to try and use the dta ecu I already have. It's an old e48 model and I'm sure if it will be able to control the vvt on the Mazda.

It will be a temporary installation

very temporary you could go down the lines of the Innovate LM2 or if your wanting it as a gauge or even just a controller you can go for the LC2.

There are tones of widebands on the market, personally I've only really used the Innovate for mobile work and Zeitronix which is installed into my Dynapack and both systems work great.
