Hello!

Anyone have a nice running MAP for the MY98 LINK ECU?

Here are the Specs wich will be there when the engibe is ready

USDM STI 2.5 shortblock
740cc´s
Header
Turboback
TD05/06
Frontmount IC

Hope you can help me

Ahh... found your post

Generic advice here... since your ignition timing will be linked to manifold pressure you will need changes based on the larger bore, but you could take a 2.0 ignition map and retard it in the high load areas to start with. Fuelling - you have roughly double the fuel flow at similar pressure to the stock 380cc injectors, and about 23% extra capacity. Adjusting constant = 380/740*2457/1994 = 0.63. These are just starting points and ideas of course. Try running on actuator control initially and get it starting, idling, cruising right before using boost. Always monitor the wideband and knock. Never copy another's map blindly especially on a speed density setup using different components.

map for a my98 2.5 550 cc injectors and a td006/05 20 g

Maybe some one can host some maps on this website.

If you need a base map you van download a link gems motec base map

harbering1, forgive my ignorance, but would those settings also work on a pre 96 link ? And if I may be so bold, is this a start map or a running (tuned) map ?

Gizmo1314 ,the map was the tuned map for my car (my98)

I dont know if it wil work on a my95 M96

harbering1,
I got your map from an old thread on 22b.com
It was the starting point for my MY97 2.5, 550cc inj, Link ECU Map

Thanks

Hope I can get a copy of mine uploaded when I sort out my laptop

Could i get a little help with this one? Why would there be more fuel at say 6000rpm at full vacum than the same rpm with full load? on the map above.

john banks

Not looked, but it could be weighted to engine load - a multiplier rather than an number in injector milliseconds.

AndrewC

John is right and the further you move away from a std engine the more skewed the numbers become as the load factors become less applicable.

Simple things like changing the fuel pressure regulator can skew the map, the effect of tubular headers is very significant.

Andrew...

thanks i was thinking along those lines as well. the link book says nothing about load being a muliplier but it dosn't really say much at all about anything.

john banks

If the difference in values between the lowest load and highest load is only a factor of about 1.5, then you know it is including load. If on the other hand, it is several times more, it is likely to be an injector time or derivative of it. Trouble is, then with an 8 bit map you wouldn't have much detail around the low load areas as the quantisation would be great.
