Lucas and t2 tuning

[andyyy]

I gauged the compensator with the amount of lag the turbocharger gave. It's trial and error, but you will get to a sweet spot where the turbo will spool harder and earlier. Some Lucas pumps (luckily mine did) can be wound all the way in and not struggle to start, so again it's trial and error, if it does, back it off a little bit.

As a rule i use fuelling to control the boosting. If you're limiting the boost and getting smoke ON boost, then you're not burning properly. It's best to just wind the wastegate all the way in (K14) or shorten the bar as much as possible (T2/GT15) (or just fit an MBC). This way the turbocharger can only create the same amount of boost for the fuel being injected. Don't worry too much about over boosting or anything, like i said on a stock turbo they don't tend to go over 22-24 psi.

I ran a TD04 with a welded wastegate on a Lucas pump and it actually went surprisingly well. The Bosch is just a lot better for compensation on boost and fuel that can be delivered when you need it.

Okay so now that I'm seeing white smoke on boost I should shorten the bar on the T2 some more and I'll see more boost rather than advancing the pump ?

White smoke/Grey smoke is incomplete combustion. Have you advanced/retarded the timing at all?

Haven't touched the timing

Literally all I have done is wound the max fuel up 90 degrees then back 45 cause it shut off and wound the compensator all the way in then out 2 turns

And wound the bar on the T2 shorter by 5 turns

Its a 1.8 BTW
