This sold years ago but I am unable to edit or delete this thread. At the very least I'd like to remove my phone number so random people off the internet don't call me.
I don't know enough about how the chip's operate except for the SD2. I would assume that there is no delay in the commanded timing but like I said I don't really know. On my car, I'm able to light the tires up almost immediately, there is no hesitation down low when everything is running...
Heat range has nothing to do with the "effective timing" Eric is talking about. That is related to the position of the spark relative to the combustion chamber. What he is saying is that projected plugs place the spark closer to the center of the combustion chamber and therefore requires less...
hey, just saw this post. I live in Cedar Park, let me know if you need anything, I won't say I'm an expert but I've been around these cars for a bit.

I hit the limit of the walbro 430 at about 22-23 psi on my 249 CI (9:1) motor with 160 lb injectors. I added a Kenne Bell boost a pump and have gone as high as 28 psi with now issues. My base fuel pressure is set at 35 psi...
On the spark plug topic, I have been running the BR7EF plugs for...
Well, I don't have set numbers but ran a modded gt500 that runs 126 mph in the 1/4 and easily ran away from him from a roll. Then ran a viper that runs 10.2 @ 138 and was behind by half a car at about 130 mph... these turbos are the best of both world's, make great power up top and give...
I'm thinking of just ignoring the knock sensor and adding the coolant pressure transducer. I plan to find the tune limit and then back off substantially. This knock sensor issue has exhausted my patience.
P.s. As I say that... one more thought, the timing chain broke in the last motor and...
Good work Paul! I told you the EFR would transform the car. The torque and response is incredible and addicting. I hope to have some dyno info on mine soon. I'm currently running 24 psi and it's just a tire roaster. Post up some more pics, I'd like to see the exhaust flange you made. Nick, where...
I've tried 2 different sets of plugs, Gap is down to .022 now on Bison's recommendation. It fixed the spark blow out issue but the knock is still present. There is no peppering on the plugs. I have not had time to mess with the car in quite a while. I plan to install the SSI map, kenne bell...
I'll double check the cross member bushings tomorrow. Thanks for the tip.
As far as the knock sensor, it is brand new with only the red thread locker stuff that comes on it from factory, and it is not over tightened. The old sensor was replaced with this one but they act identical.
Couple things to add. I looked over the tables again this morning and noticed the file in the log posted above got corrupted and switched some cells in the tables around. I fixed the tune this morning and went out for another test with the results being the same. I did notice that I had the...
