^ Nobody?? ......RE: Dizzy signal Interrupt code P1320.
I am really only worried about the Ignition signal Dizzy issue - P1320. I checked all of the connections and the engine harness today, everything is fine. I have flashed the ECU and the code comes back. I would love to know if anybody has ever gotten this code when using a B15 dizzy with a B14 ECU. The only other area the problem could exist is in the step-down harness I made. I didn't have any issues with the dizzy before I switched ECU's. If I can eliminate that using a B15 dizzy on a B14 ECU is the problem then I would know that the issue is in my adapter harness wiring....
Today I re-set the base timing to about 15*, it was set at 18* previously. I checked the E60 MAF and it reads 1.08 - 1.09 volts at idle which is fine. I also checked the TPS becuase according to Calumsult it was reading 0.4 volts at idle. My DMM confirmed this and I set the closed throttle TPS to 0.5 volts. The problem is that with the throttle fully opened it only read 3.09 volts. I noticed that the fast-idle screw was keeping the TB from opening up all the way so I removed it, I will shorten or replace it tomorrow. Now the TPS maxes out at 3.29 volts. I swapped the TPS and I get the same thing, 3.29 volts. What is going on here?
Also when I am accelerating I seem to hit a fuel cut or timing cut at 4500 RPM every time. Is this the TPS maxing out or might there be another issue?
With the adjustments I made today the car idles a bit lower/better and seems a bit smoother as well!
I can tell there is some real potential here but It still felt better with the RR ECU and advanced timing. I do feel the acceleration brake up from time to time at various RPM's so I guess the dizzy issue is definitely the main culprit here it seems....
Could really use some feedback. Sorry for the long read but I like to make sure you guys are informed about my issues!
