Hi!
Im having some major problems on cold starts with e85 10:1 cr. I fas fine running this setup a year ago but now my issue is not firing cylinders 2&3 on cold starts. Iv got new coil new plugs new ngk wires new power box next to coils. Tried different gaps on plugs. I can get car running perfect with br8's but they cant handle boost as im using br10's to do that. Really getting annoyed whats the problem. I know car was totally fine cold start with br10 plugs year ago. If any good suggestions thaks! Or link setups for cold starts.
 
Nope still starts on 2 cylinders. Going to try to play more with coils. Dunno really whats wrong atm. actually its still issue with 2&3 so coil should not be issue here as i switched firing order with 1g cas. any good ideas with this? atm there is really nothing happening in those 2 cylinders it seems.
 
Just tried swapping yet another igntion control module and new plugs is those cylinders, still the same.

Update: Was messing with connectors and fuses witch more likely had nothing to do with anything but i was able to get it run 3 cylinders so i think ill get bag of new plugs tomorrow and start from there. Possibly Cas was the issue after all and plugs just got f***ed in those cylinders.

Update
Ok bought some new plugs new o2 sensor and new battery for the car. car fired right away on 3 cylinders and withing a minute the last missing cylinder came on. Idled engine really hot to make sure what was left in cylinders is no longer there and adjusted base timing on that new cas. Overal spark seems to be stronger now (dunno yet) and hopefully i can put br10's in and be done with this fix for now :)
