Which ECU gives you the ability to remove the MAF??
Does the GEMS remove the MAF ?
i don't think the APEXi unit can, can it?
I am worried about getting an ecu & mapped with the MAF, this failing and it costing me !!
you hear the horror stories about the MAF's.
Cheers
Chris.

SIMTEK does for sure.
Speak to david at APi
MAFs are usually easy to spot when failing though; not sure you need to pay 1k for a new ECu to get around this problem. £200 gets you a knocklink fitted and it will tell you if the car is running lean and detting if you miss the other signs.

Yep, I know mate, my point was that the OP seemed to indicate that his main reason for wanting to change ECU was cause of concerns about MAF failure related DET. Changing the ECU would be a bit overkill for this; a knocklink would be much more economical.

I have tried the Autronic,the Apexi and am now running a Simtek.The autronic was great when running and did away with the MAF,but was a nightmare to get started from cold.
So had an Apexi fitted which is fantastic for starting and ideling but had to go back to using a MAF.I then had an engine rebuild and upped the power which led to a number of MAF failures(to the point of carrying a spare,for roadside repairs).So I tried the Simtek ,it starts perfectly within 2 turns and is a joy to drive,with the added advantage that there is no MAF and is fully mappable for any future upgrades.

The official line from Simtek is you need a combination of dyno and on road testing to get the best from this ECU, the same as many others.
We find the benefits make the choice to switch to this unit a no brainer.

Don't get me wrong it would always start eventually but for everyday use it wasn't suitable for me ,and it was mapped a number of times to try to cure this issue by one of the very well known companies up north,without luck.As I said when running it was a gem of an ecu but cold enrichment was always ropey.

If you'd like a comprehensive low down on the Simtek, contact Martyn @
Alan Jeffery - Engine Tuner as he's mapped more of these than anybody else.
