TTT. Tried Tick and they said they didn't know when they would be getting more. Used or new

buddy of mine broke the tail shaft housing on a 2004 Cobra T56 and we’re having no luck finding a replacement. If anyone has a tailshaft housing or a lead on one please let me know. Thank you

Okay so started it again this morning. Got to log a true cold start this time. I split it into three parts this time. I think the most important is comparing the AFR at the end of each log. By the end of this log it was idling around 12-12.5. This is still the exact same tune as the other...

Worth a shot for sure. Thanks.

Didn't end up having much time to play with it today but I was able to get two logs. Both logs are the same exact tune, the car just sat for about two hours after the first was taken. The first log is shorter and unfortunately didn't include a cold start but it does show the stabilized idle...

I'm in open loop so the O2's shouldn't be affecting the commanded fueling but it sure seems like it is. The front O2s have already been replaced. Assuming this is the issue, do you have any suggestions on troubleshooting or fixing? I'm hoping I'll be able to get multiple datalogs tomorrow to...

The units for MAF here are volts. Your transfer function should have that in the third (?) column. The first thirty or so seconds is 15-16 afr then transitions down and stabilizes like you say. I will make a 5% change and log again. The biggest issue that I see is that it drops a whole point...

Here is a log of a warm start, 150 or so startup temp. It has more than you asked for but let me know if anything stands out to you guys. I'm sure I'll still grab another one tomorrow. Thanks.

No big cams. I can go back to CL to log STFTs. The adjustments I made to MAF were at operating temp. 190-200. Correct MSE3 is 2001 cobra. Right, the af readings I've been making changes off of has been after three or four minutes at full operating temp. I remember it taking time to settle...

The lean start up is on both cold and warm starts. As far as I can tell, the Startup Cold Fuel table shouldn't be used until temps drop back to 110 in my tune. I've leaned it out with the MAF a couple times. With the FIC1000s it was first idling at 11 or so. Reduced MAF in the appropriate...

Right I'm logging in livelink. I'm currently tuning open loop so no stft's. As far as I could tell, injector duty cycle isn't available on my ECU (MSE3) if anyone knows otherwise let me know. I'll log a true cold start tomorrow. I could turn closed loop back on for stft I suppose but I don't...

O2 voltages were around 0.45-0.5 after about 5 minutes of idling. Took about 2 minutes for them to get to 0.15-0.20. I'm not sure where they should be but I'll do a quick google.

No check engine lights but it only has idle time, no driving. It's open loop so not sure if I can log O2s but I'll go see if I can log voltage and come back.

Just went out and started the car again. This time it sat for about two hours. Started up around 15-16 afr and worked its way down to 12 after a minute or two.

The car was in storage for a while and finally took it out a few months ago only to find out it wanted to idle at 11.5-12 AFR. Nothing had changed since I first tuned it so very strange. Thought that one or more of my Siemens Deka 80S was stuck open or partially open so sent them out to be...

Right the e wasn’t in the workbook. Neither were the FIC1000 injectors but there was an option to input custom injector data. I used the hpx-e excel sheet from PMAS to find the values for the tube size I’m using and just plugged those into the tuning workbook and it seemed to have worked well...

I am using an HPX-E. The instructions seemed to have answered my question and is similar to what is in Don's book. Thank you for the response, and btw, your cobra is amazing. Was reading some of your thread last night.

Thank you. I will be starting at factory base pressure to keep it simple for now.

That was my plan but I can't because of a hard limit on the maximum value for the low slope. Max value I can enter in SCT is 0.030 and the FIC data for 39PSI has a lo slope of 0.03936 Interesting that you said your car ran well both ways. Thanks for the response. I'll see if I can email Don...

First of all, thank you everyone who took the time to help me with my last thread about base pressure adjustments. I appreciate it. This time around, I have a question about fuel injector scaling since I am changing from Siemens Deka 80 Lb injectors (I think they may be faulty) to FIC 1000CC...

Finally got around to trying this a few minutes ago. No luck with the config file. Thanks again for sending it though. It gives some insight of what others are logging.

I haven’t tried it yet but it’s still useful to see what others are normally logging at least. I should be able to try it later today though.
