early rev limit.

[elky406]

i started working on the wot and heavy load tables and im running into a wall of sorts.No matter what the load wot or light load the car will not go past about 4700 rpm or so.Its repeatable and isnt mechanical.Ive checked my msd box moved it up and went threw the rev limiter wizard and moved all the ign cuts and fuel cuts to 12000 no change.Im run a tfi and its synced up real nice,was thinking about checking that again.I set base timing with spout out at 15 locked the ignition timing in the config menu at 15,tripled checked it and its good.Any other ideas?

Check the dwell value and move it down about 5 points. If that helps and you hit a higher limit lower it again a little.

Toyman is right on, play with the dwell vs rpm and the dwell value and you can usually clean up the rev issue.

will do,thanks a TON,but i first need to address the new problem,i think i may have a grounding issue,going to dive into it tomorrow.Its going to make good power though,just a snap and a 3500 to 4500 rpm pull making just over 3 lbs made 400 whp and 450tq on a very rich and timing safe map.It gives me hope that on 10lbs and 7000 rpm it will make 600 plus on pump gas and meth.
