blown 871 545 ci dual power adder system wierd cruse miss or stumble
I had the car out the other day and I notice it when it was warm between 200 and 220 degrees it acts like it has a miss at cruse speed around 2800 to 3000 the car has a 456 gear and 4k stall convertor but as soon as you step into it the least bit it goes away and pulls like a monster the whole thing is a new build the wires are Taylor 8.4 the dist. is a billet locked distributor I have the hyper fuel system I removed the 3924 plugs and installed some 3923 a little colder I am running race fuel and blower ratio is 10 percent under driven. my iac is between 8 and 10 my cruse afr is 12;8;1
I run mine in the 15 range for cruise, but mine is a 350 no power adder. Wonder if it is loading up a bit though....
not sure my plugs was a dark tanish color with some black carbon the burn looked okay to me, t reduced the heat range on the plugs from a 9342 to a 9341 but its been raining it ass off and I haven't driven it yet as far as the electrical sys the distributor is a billet locked distributor I have Taylor 8.4 wires, a msd 6al box, a msd 3 step retard with a 25 degree retard for start the other 3 stages are set for no retard, I am suspecting 3 culprits the blue wire that everyone is shielding, the cruse setting in the fuel injection, the plugs that I just changed,, I did develop another problem not fuel related but lol the rear axle housing is rotating so much under load I am bending my coil over shocks so time for a ladder bar suspension to fix that
It never ends....😁
I am dealing with gremlins on my IROC. Having to rewire right now.
It would be interesting to see a datalog when it stumbles. That would definately tell you if there is interference.
how ya get a data log I have seen that in the hand held just don't know how to record and transfer to here
Once you record a Datalog, turn engine off and wait for ecu to power down. Pull handheld and USB to PC. Take log file and add to your Dropbox account. Select 3 dots next to file name, select share, create link, copy to clipboard and paste on next post.
