Tom, I think he was talking about the EBL analysis screen shots that I added above during the logging. He might be looking in the Wideband column and seeing extremely rich values. That's mainly because I don't have my wideband connected directly to the EBL system, but I do have it checked off in the EBL Preferences tab which is why it is showing a value, albeit a rich value. Cartrax, ideally you will want to focus on the INT/BLM values with the above logs. However, for wide open throttle using a wideband, you will want to shoot for a 12.5 to 12.8 AFR.... naturally aspirated.

Hey Rob, I was thinking that I may be able to maybe starting the tune again now that I'm back from vacation, but as luck would have it, the temps are going back up this week to the 110*-112* degree range again. Ugh! Much to hot to play around. So, it may be another couple more weeks before I can start things going again. I do have a game plan for the new WB controller though and maybe I can get that installed before the tuning starts again which would be helpful.
We're getting hotter temps here as well, the next three to four days are going to be a scorcher. Once we resume the tuning, the new game plan is to make your crossfire the fastest naturally aspirated crossfire on the planet. Then hopefully you'll consider going the boost route next...

That's awesome...and I just literally laughed out loud.
Replaced my "nice and shinny" fuel hardlines with braided fuel line hose and new fittings. The hardlines were causing some issues with the new tune. I've seen this issue happen on two other CF cars, a 82 and a 84. After replacing the lines, the issue goes away. I guess you could install a fuel damper, but that would be just that much more modifying and finding the right part and I didn't want to do that. The new hose is a simpler fix IMO. Just in-case someone else wants to do this, this is how I did it. Enjoy! BEFORE
I just had to pop in per Tom's reccomendation... I may have gotten a few ideas for fixing my own mill just reading through...
Glad you all have a solution hammered down. I still have a perfectly functional 84 manual ecm. Idk how you could read any calibration data off of it but if we could... I'd gladly lend it out to help out if it does. I've also toyed with the idea of seeing if the car would even run with a stock ecm put back in it... that was the original build plan but... I may have over corrected.
Very nice work! I reached out to Bob for the L83 tune to run in my 84' crossfire corvette. Works excellent! Good throttle response and very snappy.
I do have a question tho.. Were the test mule cars all automatics? I have a 4+3 and the engine is unsure on what to do when I push the clutch in and the car is still moving. Idles around 1200 rpm while coasting to a stop, but at a dead stop settles to 950-1000 rpm after about 15 seconds or so. Thoughts?
Yo, anyone hear from Street Lethal lately? He dropped off the radar a couple weeks ago, and I'm concerned. Thanks.
I need to contact him as well and I have been trying since last weekend to include text messages with no reply's to anything. Hope all is well...OR maybe he is on vacation?
ANYBODY?
