Wide band Lambda sensors

This is just a moan about upgrading your ECU

If its something you have thought of and looked at the cost of, then here's a run down of what no one will tell you

Firstly the cost isn't just the quoted about £580

things you need:

i.e. Emerald ECU
Map switch with resistor
RS232 to USB convertor
delivery
+ all the VAT and your now at about £750 and thats just with a base map to get it started

now you have it running you need

a rolling road day £280 + vat, so about £350

think you've finished nahhhhhhhhhh

your standard lambda sensor won't give the responsive readings needed to adjust the fuel maps quick enough or with a decent enough range

Soooo you now need a new wide band Lambda, about £120 + vat an thats without a gauge to see what its doing so your looking at about £180

Total to change an ECU an get it all sorted just short of £1,300 and thats if you fit it all your self

I thought I'd just post it as its clear as mud when your looking

OMG! How much?

That is a serious wad of cash.

I've just got the lambda down to £165 an thats as cheap as it gets http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=300378724688&ssPageName=STRK:MEWAX:IT

As with anything, it is always the total price that's the killer, not the quoted price. I don't think it is a fault of Emerald in this case as the options and choices are so wide ranging that to sell as a kit would probably mean that you are paying for bits that you personally didn't need.

Yeah thats true, and it will work as it is

just a good excuse for a moan...lol

roll on pay day I've spent it already ....lol

but you must admit its a bit of a surprise to find the price doubles to get it running at its best

Emerald as a company I must say are amazing, so helpful and bend over backwards to help, sending extra instruction, maps or advice

i just got a 2nd hand emerald and loom adapter for £450, and going to take it for rolling road set up in a few weeks.
all in all i budgetted about £900 for the swap...
i dont see that as being expensive or un-reasonable for what you get...

Especiially when something like a motec ecu starts at about £4000!!!

Also bought a 2nd emerald to run my Jag V8 that im putting in my old lotus which should be fun!

£1000 just on 2 emeralds in the last months! oops! lol! shockingly Mrs Oz hasnt killed me yet, but the MGF is her car, so i guess she doesnt mind if we both get an Emerald! at least i dont have to buy her diamonds!

I also have to echo your comments on Emerald, even though i have 2 2nd handd units they are being super helpful, and my friend Ian who is helping me with the V8 knows Dave quite well, says hes a top chap.

The only problem I'm having at the mo is the first couple of minutes starting in a morning, but people have been so helpful

I've had loads of maps sent to see me through till I get it on a rolling road so if you need a base map to work from give me a shout

Dave Andrews who did my ported and polished head, plus Piper 633's and vernier pulleys provided me with a map for his ported and polished head, piper 633s, and a 52mm throttle body...
If thats any help to you i can send you that as a good basis to start from...
im using that as the base, then mapping on a rolling road (only difference in my set up is 48mm Tb instead of 52mm) so should be a very minor adjustment.
This map was making 151bhp at the wheels in a K-Series Elise with a 4-2-1 Manifold and all the above bits.

Btw why did you need a wide-band lambda? never heard of emerald needing that before... was it pre-cat or post cat?

yeah cheers any map that I can use is always good, even if it just sorts my cold start

I was looking at the adaptive mapping an they recommend the wide band for that, an in all honesty a gauge to show if its running lean when using Nos would really help stopping me melt pistons too.....lol

lol, well then thats your own silly fault for useing NOS! crazy man!

What is your car pushing out without the NOS?

Message me your email address and i will send you a copy of the Map i have

God knows but it ran really well, and 55bhp extra with the Nos, its so addictive though...lol

I'll send the PM now

So, do you think the rough starting might be over/under fueling when cold?
