O.,

The difference is 110 degrees between the coldest and hotest cylinder.
A colleague of mine says that is a bit high for a fuel-injected system.
Is that right?


Not really. Absolute temperatures are not that important (in the context
of leaning). Go to www.gami.com and run their lean-test to find the
spread between when your first and your last cylinder reach peak. THAT is
important - and you can change something by rotating the nozzles.

I would recommend you read the engine management columns by John Deakin
at www.avweb.com.
