Delkevic exhaust, experience?

[Jambo_imp]

Jambo, apropos your comment on the Dynojet maps, [url=http://cb1100forum.com/forum/showthread.php?tid=4700]this thread may be of interest. It may simply be that Dynojet have not had access to sufficient bikes with sufficient mods to develop the maps.

Disclaimer: I have no idea, really, whether this is the case. It may also be that whenever one of their agents develops a map it goes into a central pool, but there has always seemed a scarcity of CB1100 maps.

Well truth be told, there are a lot of bike models out there. Perhaps if they exhaustively tested every model and combination and permutation of model vs aftermarket exhaust and filter, the initial cost (passed on to the consumer) of the PC would triple. Also if they had the best stock maps for every scenario, why buy the Autotune? That would only have value if you are an air-fuel ratio expert over them, or you just have your own notion as to what it should be given your circumstances. That the map provided with aftermarket pipe and no aftermarket air filter will work, well yeah, but it is not going to be optimum. Maybe still an improvement over just the ECU by itself.

I intend to do the exhaust in stages. Maybe just shakedown after temporary dry fit (no RTV and reused stock exhaust manifold gaskets), see how lean it is mated to the stock ECU, then return to do phase two with just PC and provided map for the CB. Then install the Autotuner with the welded wideband O2. Phase three with Delvkevic provided crush washers and RTV joints to properly seal, then tune. I assume multiple shakedowns will be required for phase 3A, 3B, 3C...Haven't fully decided yet. I do know I am anxious to ride the bike. I just got my tag Wednesday (2 days ago), and really have not had any bonding time with it before yanking the stock exhaust....
