Glad to see that you have made some progress with this! As Rod as mentioned it is a Jenvey sensor, the TP1. The TP11 they offer has the same linearisation and is made by Variohm, the same people that ...

In my case, there were warning signs. I just didn't notice it. MoTeC's i2 data analysis software has a powerful feature that highlights diagnostics -- it's just that I didn't know that until after the...

Thankyou John, My engine is finally running well and the TPS is functioning correctly. I have not removed it to get a part number but I assume that it's a different part from your SR8. Don

Sensor itself is normally the problem with these. Glad you have sorted it. Keep an eye on the reading, in earlier cars there is changes to the map depending on air temp but the sensors have not always...

Changed the air temp sensor and fixed the issue. Still does not understand how to read the ECU pinout.

FWIW, my left-bank TPS failed at Miami-Homestead this past weekend. 2 years old, maybe 40 hours on it. I'll be replacing mine annually from now on. 😯

For reference, I just got a dealer quote on Radical's new cast uprights: $1,748 ea.

Thanks to Charlie, David and Rod. My TPS has some numbers on it so I'll see if I can find a new one with those numbers. Might not be like yours since my wires are Red, Yellow, and Green. Trying to get...

Hello Dan and Charley, Some progress today. First thing I did was make sure that the engine would run. Without changing anything, it started and idled; however, it was a low idle, ran rough and stumbl...

@speedstarincdjb Hi Don. I have a recent story to tell about TPS which might be relevant; I assure you I do not mean to hijack your interesting thread. I was at the Radical Cup Sebring official te...

@davidf ... Great insight David. I don't know much about the TPS either.. but I do know where to buy them as I purchased a spare based on some previous comments about their reliability. Here's what ...

@rjbender Hi Rod. Yes, and your way makes sense. On the main wing, lowest down force would be the 4th from the bottom. "From the bottom" is specified in the user manual setup sheet, and I have int...

The Handling Guide has this to say about aero adjustments: This is a very brief description, but that is basically all there is to it. To determine whether a change has helped or hurt, one can ana...

My perspective is just for SR3. TL;DR: hole 3 from the bottom on the main wing, 6 from the bottom on the subwing, and no diveplanes on the nose. Very few race teams/drivers will run dive planes on...

Rod, Good advice. I can see now that tapping on the drive shaft end would have worked also. I saw that when I was working but was unsure since this was the first time I had done this on a Radical an...
