Big turbo/fueling/mapping?

[topher]

it'll run, and be okay for running in if you're staying off boost. Last time i dyno'd a car with a similar maf/injector setup was only fuelling at about 0.95 lambda under boost. Its a bodge to keep the fuel trims in check but the ecu will have a hard time figuring out what is really going on with the engine load.

There you go mate, the proper answer 

[topher]

the proper answer would take several pages of text, i summarised

Nice one thats good to know, at the mo it won't boost properly at all, get to about 3.5k revs, starts to really boost then it starts to judder. Havent pushed it as breaking it in but pretty sure it is down to a leak in the intercooler pipe work mixed with no N75.

Instead of running the n75 I'm running a electronic boost controller but can the ecu take that in to account also? or as its not plugged in is it going to keep going into limp?

[topher]

the judder is probably fuel cut. on a setup like that you would really benefit from an AFR/lambda gauge.. i know they're not cheap but it could save you a lot of money in the long run. i'd plug the n75 in (not plumbed in to the pipework obviously), set the mbc to about 12 psi and see what happens

It the HKS EVC 6 boost controller so not a mbc, lots of settings of which I don't much yet but hoped it would help. Will plug the n75 back in, cheers

Is the AFR/lamba gauge to do with changing it to wide band? read some bits about that but didn't understand it properly.

[topher]

no need to do the me7/wideband upgrade, just a standalone wideband such as innovate. it'll mean adding another boss in to your downpipe for another o2 sensor. It won't be used for any kind of fuel control, its just so you can keep an eye on the air/fuel ratio

Cheers have pm'ed you about this, want to get the max out of my setup, is there anything else ive over looked?

Cheers

I ran yellows and VR6 maf with no fuelling changes in map and overfuelled causing fuel to get into the oil.

Nixxy good!

[jonrandom]

Something like that is my worry which is why ive put the standard ones back on and standard maf for now, not that it will run with the maf plugged in at the mo anyways
