Litchfield M4 stage 1

Is the Litchfield stage 1 worth doing on the M4? Seems cheap enough but is it noticeable and complimentary?

^^ I think that they will charge you for it.

Litchfield will strongly encourage you to get their crank hub fix at the same time, with tales of terror about borked motors. The crank hub fix costs about the same as the map so it doubles the cost of the map if you get it done as well.

Whether you do actually need the crank hub fix on a stage 1 car is open to discussion. CS versions of S55 motors run higher power from the factory without the fix.

If your car is in warranty and you get the crank hub fix, I would say thats definately the end of your warranty because its an obvious mechanical modification and clearly not stock.

I hear lots of positive reviews. You can but MHD/Bootmod3 and flash the car yourself with an off the shelf map.

The M4 GTS runs 500bhp and 600Nm with no change to the crank hub. I would use those figures as threshold for reliability and durability.

That's a fair point about the CS, never thought of that.

speak to evolve automotive aswell since they remap them too

If your car's in warranty and you remap it, that's the end of your engine/drivetrain warranty anyway.

Thanks guys.

I’ll think on it.

I had the Stg1 map on my M2C and seriously brought it alive..... I've now gone further and also had the full hub fix done as well

Similar to Steve's post above, I have Bootmod3 stage 1 on my M2C and it has transformed it. Couldn't go back to stock would feel very flat and weak by comparison.

Crank hub fix is 1850 at Litchfield or can be done most places for around £1800 now. Also wouldn't worry about it too much at stage 1. But worth bearing in mind for the future.

They might offer you a catch plate. It does nothing, waste of money. I know two people who have spun crank hubs. Both their engines were fine afterwards. And both had Litchfield catch plates fitted when they spun.
