Well... In the name of research it have tried to take little baby steps with my turbo. Adding a few minor adjustments along the way to see what small increments will get you, instead of making one big leap. I can tell you that I am learning stuff and I haven't destroyed anything, but it can get frustrating at times and today was one of those times. Anyway... on to the story.
Here is a link to my first venture to the dyno right after the install:
Here are the specs on the particulars:
Greddy kit [With the 12:1 disk]
Custom [Jim*] RX-7 intercooler
Installed after the initial "after turbo" dyno runs:
Bipes [Pulling 4* at 3k-4k and 1* per 65* of temp]
Olderguy's O2 Clamp with the original "factory" settings
NGK 7E plugs
VooDoo Manual boost controller
Here's the problem:
The car ran great initially, but I was encountering a little pinging on hot days so I went ahead and installed the Bipes and set it as shown above. In the last few weeks I have installed the plugs, clamp and MBC. The car still runs great and I am still getting no pinging. During the dyno run we got a lean spike all the way up to 17.9 right at about same time that the car is hitting max boost. But it only last for like a second and then richens up as the boost tapers off. [Sorry... I was so brain dead thinking about the lean spike that I forgot to get the dyno files, but I hope to have them on Monday to post and we can analyze them.] Conversely I am also getting a big boost spike that seems to go up to about 10 or 12.
First off I am going to check the dang MBC. I must have it tightened up too much... Sheeze. It is obviously causing the spike in boost and then it drops off dramatically because the Greddy waste gate actuator is so weak. [I need to quit goofing around and get a boost gauge and a real wide band.]
Secondly, I am going to go ahead and install the Walbro 190 hp and the 1.8 injectors. [I was stupid to not have already done this, but I thought that the simple addition of the O2 clamp alone would have smoothed out the fuel for only the little amount of boost that I wanted to increase.]
Thirdly, I am going to either buy a pack of disks for the vortech or either install a MBC on the vacuum line running to the FPR so I can adjust it on the fly.
Fourthly, It's kind of weird that I am getting no pinging with that lean spike.
Fifthly, I am going to quite drinking so much when I work on my car.
Frankly... I can't see where the the O2 clamp is doing anything for me. I think I have it installed correctly. I ran a "T" off of the vacuum line feeding the Vortech. Ran the line through the little hole in the firewall behind the washer bottle. Ran it into the pressure switch. Capped the other side off. Wired the signal from the O2 sensor to the "NC2" plug on the pressure switch. Wired the "CO1" plug back to the ECU, and wired the white wire from the O2 clamp to the "NO3" plug on the pressure switch. I know I have the other stuff wired up right and the LED is on. Maybe if I get the other issued ironed out everything will start to fall in place and the benefit of the O2 clamp will become more evident. Right now the A/F ratio looks like a roller coaster ride.
I thought I was doing so good getting everything installed and running so good, but now I feel like a total dumb *** trying to get the boost right, the A/F right and the whole thing tuned correctly.
Comments, advice, suggestions? [I promise that you won't hurt my feelings or self esteem.
