| Question:
alan, ive recently put my high torque cams into my corsa [x16xe - running map sensor]
on the correct timing marks im getting too many pulses to my map sensor....
if i disconnect the sensor they run fine.....but i lose all throttle response.
so alternatively i advanced the exhaust cam 22 degrees, which removed the split overlap (in effect)....
although i now have a lot more top end, ive lost all bottom end power with a huge flatspot (all the way to 2k rpm):(
any ideas? |

| Answer:
The cam timing shouldn't deviate very far from the designers specifications. 22 degrees is a huge deviation! I'm wondering if there is an error somewhere, or maybe if you could consider re-siting the map sensor feed?
Are you using vernier pulleys with a protractor? |
