Its actually easy enough to guesstimate safe top line timing if its a simple spec though and wouldnt need anyone to risk a poor customers engine with testing which I would simply not do.
What turbo/CR/head ports/cams and injectors are we talking about on this engine, with what target AFR?
I could put up the sort of figures I would expect to see and you can then put up the real ones Danny.
Ok thats fair and a better soloution..
The actual cr was not known but it was alot lower cr than 4is and the ignition map obviously represents this..
The fuel map is also totally different too
I will get all figs posted and as tony has the engine in bits he can confirm the actual spec it was..
cheers danny
