  1. If I remove my airpump on my Spec.B, do I have to worry about the cold winter months up here in NH? I have the CNT DP installed so I assume the exhaust gasses will warm that high flow cat up quickly, but I just wanted to double check it.
  2. My wife gets in the 08 Spec.B this morning. She shuts the door and immediately she says, "it's so cold in this car now I can't stand it.. Whats the deal?" I reply, "Just got Cryotuned".
  3. We did the full leak down before pulling the heads and I was losing 18 psi out of the exhaust valves.
  4. Well, I had the Spec.B back at the shop and they double checked all the electrical. The logs look decent too. Can't find anything wrong peripheral to the motor that would cause the ruff idle. Even though my compression is ok.. I think the only thing left is to tear the top end down and do the valve job.
  5. Update: I took some fueling logs and noticed that my Fuel pump duty cycle was high relative to my injector duty cycle. Seems like Fuel Pump duty cycle is 100% and Fuel Injector Duty cycle only ever gets to about 38% This seems suspect to me Link to the RomRaider Logs https://drive.google.com/?authuser=0#folders/0Bw6BnMiITPBpS09pTkZ5T3FlLTA
  6. I recieved my tactrix today! Below is the google drive link to the Learning View screen shot. https://drive.google.com/?authuser=0#folders/0Bw6BnMiITPBpR21DaXNTanRTUEE I am little out in the 1.20 out of range in 0 - 5.60 but seems like other than that my MAF is scaling almost perfectly. No knock correction which is a relief. But miss - fires on all four cylinders The shop is going to check all the grounds and ECU pins. They did take the intake manifold off when they did the injectors and cleaned and secured all the grounds but they will check the others. What do you think I should log in RomRaider I was thinking the closed loop fueling parameters?
  7. Ok cool, I am going to order up the Tatrix and get set myself set up for data logging. I eventually want to go to a stage 1 map once the gremlins have been solved and this will be a good segue/learning experience.
  8. No I haven't looked at the learning view. I was reading the access port V3 Spec document and Was looking at the all the data logging parameters. I was also thinking of maybe getting tatrix and Rom raider. But was nervous about bricking my ECU. Where as access port seems more tested but exponentialy more expensive. Well, technically not exponential greater but feels like it.
  9. Update to the 08 spec b the the elusive P0301 and P0304 has returned. The only time I get the CEL condition is when I put the car in first gear or reverse apply gas and let out the clutch. I also can notice a ruff idle when I push the clutch in and come to a complete stop. Idle is ruff for maybe 3 seconds when the car has stopped moving and then something adjusts and car smooths out. The new injectors, MAF clean helped out tremendously, the car rips now except when I hit the two above conditions. Could O2 sensor cause it? Has 109k on the clock and they haven't been changed. Also was thinking maybe fuel pressure regulator. I did notice a drop in mpg with the new injectors from about 25-26 mpg too 23 mpg. This seems like a good sign to me probably a little to lean before. But still didn't cure the pending missfire problem.
  10. Update to the Spec B. Range Automotive in Somersworth NH replaced the injectors and seals, cleaned the MAF new intake manifold gaskets and reset the ECU. Had a cycle compression test done while the intake manifold was off, numbers were: Cyl 1 - 140 Cyl 2 - 145 Cyl 3 - 130 Cyl 4 - 135 Range Automotive didn't seem to think that a rebuild was necessary with the compression test numbers. Idle seems much better and no miss fire codes so far
  11. Thanks for the input, Talked to the shop today. They are going to replace injectors and intake manifold gaskets. I am up in NH and read they can be trouble in cold climates. They are also going to double check coils and do a compression test. Keep fingers crossed I don't have to pull the heads and rebuild. I had NGK plugs put in when I first noticed the slight rough idle.
  12. I have an 08 Spec B with 109k I have slight miss at idle that appears semi random. Will idle ruff at around 700-800 rpm this seems more consistent at first start up, after driving it will appear randomly at stop lights Threw CEL with missfire codes (banks 2/4 if memory serves). Tried Seafoam treatment and that seemed to really clear things up for a couple days but then the ruff idle came back. I am having the injectors replaced today (just going stock) and I am hoping for the best!
