Between wedding and 2 kids B day parties… I had some time to take the car on a drive to get groceries…..I was just sure to take it to the store a few exits away.
The good news-the BoBo Tach works GREAT! No drop in RPM, no erratic signal-nothing. So I would assume that the signal coming from the ECU is good-and my VDO tach is junk.
Bad news-I noticed a little smoke on the way home after a pull. Could not tell if it was on decel or WOT. The car has NO catch can or evac of any kind, and that has solved a lot of issues like this in the past-so that will be the next mod. Car felt strong and was not running hotter than normal-so I won’t worry about the motor just yet.
Next, did some test pulls and shifted when I “thought” I needed to shift. Using my phone in a very sketchy manner, I found out that I short shifter 3-4 at 5600, and 4-5 at 5400!!!!! No wonder the car fell on its face on the track!!! Evidently I have to calibrate my ear’s tachometer.
The best news-winding 4th to redline netted very good transient response in the shift to 5th gear. It still takes more time to recover than the first 3 shifts, but it was 100% better than it was on track. I am hopeful what with no other changes beyond a proper 4-5 shift that I will pick up some MPH and ET. Once That is sorted, I can try to hit my 2nd boost stage earlier and/or turn up the 2nd stage boost level.
I have some things to do before my next track visit, but I am excited at the prospects of improving the performance with no additional $$$$ added!
