Ok Decided I am getting as much info as possible about going Emerald standalone ecu and in one place, so please feel free to post. The z22se ecu has; crank sensor fuel mixture lambda sensor (before cat) catalytic convertor condition lambda sensor (after cat) air intake temperature sensor throttle position sensor - built into fly-by-wire tb coolant temperature sensor MAP sensor 4 x injectors coil pack EGR valve knock sensor supercharger standalone ecu needs; crank trigger wheel + sensor fuel mixture lambda sensor air intake temperature sensor throttle position sensor (manual throttle body) coolant temperature sensor MAP sensor 4 x injectors coil pack Copied from Vocky Emerald K3 ECU Full ignition & injection management system Includes :- PC control software, base maps, operator's manual, PC communications lead, and ECU loom-plug & pins. £667 (inc vat) Cable operated throttle is needed Rik got the last base plate from Eliseparts, I believe they can ordered direct from Lotus (unless I have one Just like Riks to copy ) 60-2 or 36-1 (according to Emerald) trigger wheel, direct from Emerald £33.00 for the 60-1

Find out how the Z22SE ecu gets the firing order from the ignition module (= "cam sensor"):

[vocky]

webcon also sell their cable throttle set up as a complete kit

then you need a billet 70mm throttle body which accepts a Throttle Position Sensor

edit;
the company selling them is IK engineering (for when the listing ends and nobody can use the link)

Air temp sensor (NTC, M12x1.5mm thread) £10.00 Coolant temp sensor (NTC, M12x1.5mm thread) £10.00 Throttle position sensor £23.00 Marelli MAP sensor, 250 KPa £67.00 Marelli MAP sensor, 300 KPa £87.00 Delphi MAP sensor, 300 KPa £49.95 Inductive crank position sensor £25.00 Off the Emerald site, any idea why there are 3 types of Map sensor and which is the best? Would the Lambda/s be a wide band one/s? Just spoke to Dave Walker ate Emerald , VERY helpful he said they can set the ecu up to allow OEM coil pack also he said he can do a plug for the ecu/loom Biggest thing will be the 60-2 trigger wheel setup so need to get one sorted.

webcon sell their z22se crank trigger wheel and sensor with correct mounting bracket too

[Exmantaa]

The LSJ engine has a Bosch 0 261 230 040 TMAP sensor (20-250 Kpa) with an integrated temperature sensor that bolts directly into the manifold. (Bosch have several TMAP sensors ranges, up to 400 KPa.)

[slindborg]

use the GM temp sensor too

[NickB787]

great thats another one down

Idiot comment here...

What's the difference between a 250 KPA and 300 KPA and I know 50 before Joe comes on line

[vocky]

you will probably require the 300kpa it's just how much range the sensor has

[theolodian]

Pascals mean power!

[slindborg]

I'd go for the 300 for future proofing

Kpa, pressure measurement. What you need all depends on what boost your running, 1 Bar = 100kpa = 14.7psi, atmoshere is 1 Bar so if you want to run under 1 bar of positive boost a 200kpa sensor is plenty. If you want to run more than 1 bar but less than 1.5bar than a 250kpa sensor is fine, more than 1.5 bar (21.8psi - I really don't think your going to boost 21psi with a charger, infact probably no where near to 1 bar) than you'll need a 3 bar or 300kpa sensor, but thats real overkill if I turned the boost on my MX5 to 2 bar it'd make about 400+bhp before it blew up

Emeralds an ok bit of kit, but the softwares gash. I'd only get one if your planning on getting Dave to map it, he is very helpful and is supposed to be good, although hes a bit on an n/a man. His last ecu didn't even support boost with a map sensor, he mapped on throttle position which was just silly.

Thanks guys,

64mm / 2.5" ~ 27.5 psi
70mm / 2.75" ~ 25 psi
75mm / 2.95" ~ 22.5 psi
80mm / 3.15" ~ 20 psi
85mm / 3.35" ~ 17.5 psi
89mm / 3.5" ~15psi

These are the pulley sizes + Bar I will be running @24 psi as I will be running a 2.9" from the standard 3.15" that I have now.

So 300kpa it is then

I gather Dave likes N/A but he seemed willing to help. His software must be mappable by other people though?

They say they come with a base map but for a s/c setup? they would have to have the car for this.

Once you have a base map how easy to do it to modify yourself?

The LSJ engine has a Bosch 0 261 230 040 TMAP sensor (20-250 Kpa) with an integrated temperature sensor that bolts directly into the manifold. (Bosch have several TMAP sensors ranges, up to 400 KPa.)

thanks, better start looking then

[NickB787]

one thing I found was this article for people like me who are new to this thing
emerald site

[slindborg]

a base map will be knocked up from experience and guesstimation... its not mega hard to be honest. Plenty of folks can map emerald, just need to find one you like

[NickB787]

This could be a problem for me if I we to go Emerald and Dave Walker was to set it up

Off Emerald web site

The rolling road measures a maximum of 270bhp at the wheels up to a speed of 160mph. Depending on transmission/tyre losses this equates to a maximum flywheel figure in the region of 300 – 340bhp.

Not enough

[techieboy]

Not enough

Looks like they've mapped more powerful cars than that on their dyno Nick, they just need to be a bit careful and probably don't run it all the way up to full power. Pretty easy to make an educated guess to the fuelling/ignition requirements up the top there I guess, once the bulk of the mapping has been done. Plus it can always be tweaked by logging the various sensor outputs after a road or more likely track session.

or they have a "switch" that goes very inaccurate but lets you go higher.....

Or talk to the two steves at track and road in rainham (essex)
