Maf---less

[MatrixXXx]

My MAF is playing up again, any one gone maf less, I understand it needs some programming ? What's the cost of a replacement vs MAF less plus programming?

[ringram]

Tune will be cheaper to disable than buy.
It depends what the base fine is like.

5 min job if tune is good.

Unsure what car matrix has, nothing in his profile, does it not depend on what mods have been done to the engine on how easy it is to do ? If an engine is FI is it just as easy to go maf less in 5 mins ?

[ringram]

In theory yes.

In practice lots of tunes take shortcuts..

Which if you remove maf are revealed.

Oem no problem. As it's done fairly ok.

Understand ringram, was unsure what state of tune matrix had as nothing on his profile (btw that is annoying when asking for info) I know mine was more difficult to do being FI with non OEM injectors

[ringram]

If its fully tuned as per OEM with map sensor calibrated for manifold pressure and base fueling set its fine.
5min job..

Otherwise its full retune to do it properly time..

My maf less retune was with a 2 bar sensor and lots of time to do without a basic tune

[ringram]

Yep thats the way, 2 bar for FI definitely

Standard 6.0 VXR8, just a walkinshaw oval exhaust..

I understand there is a default setting based on a fixed table, where would,i get the tuning/programming done, based in York, work in stone , staffordshire? aprox cost?

As ringram mentioned, should be easy matrix, be handy to add that bit of info to your profile, just makes it easier for replies

Done! dont know where it went.

[ringram]

Good question. AAS might?

Greg at Protune is just south of Birmingham. Thats where Craig gets most of his stuff tuned.

Depends on how far south you want to go. If you bought a license with you Id do it for free.
Ask Mr Fish and WPUK as well if you are down this end of the country.

[MatrixXXx]

What do they need exactly, something to program the engine management system? GM?

[ringram]

efilive or similar plus braincells allocated to the correct part of the internet and rtfm process etc.

Reply from Walkinshaw

"Yes the MAF sensor can be removed but it will need remapping which is £600… May be better off just replacing the sensor.. Thanks"

[MatrixXXx]

would it also give 100hp extra and better fuel economy?

[ringram]

As per previous mate its all 100% dependent on the tune. If the tune sucks the retune will take ages and may well give loads of performance and economy.
