Street stock ecotech problems

[delcowizzid]

vn fires them all at once yip

 

[delcowizzid]

and noone else running an ecotech has this problem i gather

jayme had a good thought before does it have a vn coolant sensor and IAT sensor in it the VS coolant sensor was different to vn maybe its been tuned to suit but just an idea if guys with buick V6's are using the same tune and sealed ecu as you use on the ecotech well that would cause issues

I haven't found anyone else running under these rules everyone i know are running the vr engine before eco but were having trouble with them doing the same thing but we think it is bore to piston clearance and the aftermaket pistons
since they had them honed more to give them clearance they have been fine but the eco still spits the edge of the piston

there is a pleum spacer to make it presurise more equal but we are not allowed to use them and inside the pleum there are 2 humps which direct the air in the lh middle piston witch would lean it out but we carnt remove them not allowed.
do u think the bigger inj will work or do you think it will cause more trouble eg like bore washing

mate i was told to run the vp ecu not the vn one.
Try fitting a vp ecu. the program is a little different.
