Yep. I understand my delta T being large, but I don't know what is "normal".

I have a huge 24x12x3 bar/plate (same core as Tom/BRGRacer) intercooler waiting to be installed, but I'm worried about that ****** blocking airflow to my radiator.

I like fast spool, but I like power more. If I don't like my numbers at the dyno or the increase I feel in my butt dyno after the I/C then out go the turbos.

I've got one too. Little IC is doing an adequate job... maybe summer will push me to install it, now that I have a reasonable tune.

Aw I think i killed my LC-1....was boosting around taking some logs...had to redo my map in cruise as my timing was off this morning and I reset at lunch, I had it at about 4° when MS thought it was 10°. So cruise and idle AFR got effected, surprisingly boost was still dead on.

Anyways, got to a point where i was happy with the map, saved it, and started boosting like crazy to take some logs. Shifted and had to hit the brakes and the gauge went full rich, not lean, like a heater error. Waited for it to cool off and return to normal, but it didn't happen pulled over, turned it off, waited a few, turned it back on, same thing, full rich gauge, no readings on MS.

The map is good enough where I don't need the WB, but WTF 2 days before the dyno. Letting the car chill for a bit and going to try again later, if no dice, then I'll pull the sensor and recalibrate, hopefully that kicks some light into it, but we'll see how it goes later.

Anyways, hitting close to 15psi now (ran out of threads on my MBC). It's fun, especially with my timing back...hahah.

I had my LC-1 randomly recalibrate on me while the car was running once. It did it while I was firing up logworks. However mine was showing 22AFR until I did the recalibrationg.

Hopfully yours is ok.

nope, turned the car on nothing....hooked it logworks, showed low voltage error 9....funny never had a problem before.

remove the sensor to perform a free-air calibration.

turned the car back on, started heatinig %....it was still heating taking forever....got stuck at like 76%....then started a heater calibration and threw an error 8 for sensor timing.

Matt is nice enough to provide a spare sensor to try out....ill try that tomorrow and see if that works.

btw, error 8 is:

1. Sensor overheating.
(The Bosch LSU4.2 is rated
to operate at a sensor
housing temperature of < 900
degrees (measured at the
bung) for maximum accuracy
and control. When this
operating temperature range
is exceeded, the sensor can
no longer be accurately
controlled. )
2. Sensor is damaged

i have a heat sheild (not copper) guess I need the heatsink as well...this sensor lasted over a year...wonder why it died today....

That stinks dude. The failure happened to occur just as Innovate is releasing the gen 3 LC. Hmm...

My E8 went away after doing the full calibration process. Like Jay's mine also once decided to go through the calibration process while driving. And I know it's not that stupid ground wire some how contacting because mine's clipped because I have the xd gauge.

It's stupid errors like that why open loop boost fueling is still so common, despite the low cost of wb controllers.

My core is 24x12x3, overall length is around 30 inches. Also my end tanks are vertical so i can go over the radiator. I'll be installing mine the week after next. Your size will fit easier.

ahhh - that core is huge. Mine will fit with the a/c drier up front. Tim that core should be good for 600hp... excited to see what follows that!

Brain, are you running the stock motor at 15psi?

From most of what I have read that tends to kill the rings pretty fast, although most of what I have read was written by people who have never seen 1psi.
