can you live map a rs turbo mfi ecu ?

 

u cant map the ecu. its all mechanical.

 

yeah but im sure ive heard people say how shite off the shelf rs turbo ecu chips are and they say go to ahmed bajoo for a mapped chip

 

The ECU isn't mechanical...

But like everything before EEC-V it's a read-only memory. So if you want to modify it, you have to solder another chip into it.

 

mate do not go for the ahmed bajoo chip! thats wat i got at the moment. thing is its retarding the ignition and not allowing enough fuel in, which is losing me about 20bhp.

Go for a unlimited boost chip imo.

 

Why not just get rid of the skanky MFI and go for something which can be live mapped!

MFI is shit, and thats that

 

if MFI is shit, shud i change it for EFI?

 

EFI is the way forward!

 

how much wud it cost for a efi conversion?

what are the benefits?

 

Having it fully mapable. MFI has its limitations and is hard to get a good fueling ratio through the rev range.

 

It is the way forwards but for up to 220bhp it's not required. Above 220, I would start to look for a decent EFI set of some description.

 

Efi's the buisness i am hopefully fitting mine soon

 

All 'chips' are 'unlimited' boost

Anyone who tells you any different should be avoided like the plague.

Or if you iz one of doz who does beleev

then

In a RST, don't mix up the fuelling system and the ignition system which are two totally independent systems.

Fuelling is handled by KE-jetronic, a mechanical fuel injection (MFI) system by Bosch, which isn't completely mechanic because it has a electronics control box. You can't really call it an electronic computing unit ECU because it doesnät compute anything. It has nothing digital in it and certainly no programmable chips. So, back to the question, "can you live map an MFI ecu?", no you really possible can't.

The ignition is handled by ESC-II unit which on the contrary is digital and has a programmable chip. IMO, this alone makes it possible to live map, not sure if anyone does it, but it certainly has nothing to do with the type of chip, as the chip itself does not need to be used in the live mapping, but an emulator. But then again, and for abvious reasons, the chip of the ESC-II unit can do nothing for the MFI.

 

Jesse - the problem is that the data is stored in the processor itself, not in an EPROM.

All chips are not "Unlimited Boost" Some raise the limit but do not remove it.
