Hey jimmysuite, How much was it all together to get your head ported and pollished by PG. I know it is about $500 for the service, how much was it to ship the head? Did you have to ship it by freight?

shipping in my own packaging - $0 (paper, bubble wrap, thick carbord box)
UPS to PG from my house with $400 insurance - $22 ( i only live about 3 hrs away from PG)

Just added the 626 mani to the build! - Thanks Ken.

You should have just made a weekend out of it and drove there and back. Probably would have only cost ya $120-150 in gas to do so. So when is your head going to be done??

About a week or so.
And shipping only cost me 22 bucks, which is alot cheaper than driving.
Way off topic here, but 3 hours at 60 mph is 180 miles. Round trip of 360 miles. Sounds more like a $45 tank of gas.
I'm guessing the ceramic coating is pretty durable. You wouldn't want it to chip and come off. A piece of loose ceramic would do bad things inside the combustion chamber.

OH, my bad. I was thinking it costed you $400. Wow! that is a deal. The head must weight quite a bit, I am suprised it was only $22 to ship it.

Plus the time wasted driving.... (i'd like to think my time is worth something
)I checked into the durability before I got it done. Both of the coatings bond extremely well to metal (see the links) and the shop said that there are some of their customers who get it redone every few years. Even then there is still coating on the pistons.
that's a very good way to describe it, exactly what i was thinking.

Pistons still aren't in the motor yet, and head plus goodies from PG should be here early Feb. at the latest.
I hate the waiting game!

I have been reading through the microtech and innovate install/tuning manuals and I have a couple questions about them. The innovate has two output wires one wideband (7-22 AFR) and one simulated narrow band. (~14-15AFR) I'm guessing the ECU needs the wideband signal and if it does can i use one of the MT outputs for my wideband AFR gauge? I guess im confused bc what is the point of having a wideband gauge if you cant get a wideband signal to it. Should I install one before the other or at the same time?
Also, with the standalone and wide band can i eliminate the two O2 sensor system? (ie just use the wideband O2 sensor with no CEL) Thanks in advance.
Finally, I know LW had problems with idle issues. I read in the manual that the MT can controll idle via the Throttle position sensor instead of the vacuum reading for cars that may have an erratic reading at low rpm's (like cars with large cams and overlap) What did you do to fix this LW? Any tips/tricks for install of the MT?

control idle via TPS??? didn't know it could do that...
what i did to get my idle control going well (using target RPM and map tuning), was i went through all my vac sources and made sure i had no leaks, so I could get a stable vac reading, then cracked the throttle plate open slightly until the car would idle by itself at around 800rpm whilst hot and under no additional load... I then used the microtech idle control settings to bump that up to 1000rpm....added an input condition for the air conditioner idle up, and it was done..its far from perfect, but it does work reasonably well

in the blue MT installation and prog manual
Pg 14 -- 1. Idle -- the first sentence is:
"There are 6 set-up screens for the idle function , from 30"Hg to 0"Hg OR 0% to 96% TPS"
Later on Pg 14 --- Screen 8 - Load (Normal Mode) --- bottom paragraph
"Low or irregular vacuum applications such as.... performance engines with large cam overlaps and radical inlet designs may have wide vacuum fluctuations at idle and low revs, which will give false readings proportional to load. The TPS function overcomes this problem by sensing engine load usinf the TPS rather than vacuum as the primary load source. To configure the MT to operate in TPS mode go to screen 31. default is LOAD=MAP change that to LOAD=TPS.

Oh, that simply tells the microtech when to drop on to the idle map....
its not actually controlling the idle control solenoid....that setting is auxAir_min/max/rpm etc etc...
tuning on map with the twiggy cams is perfectly fine..

^^^ it still sounds like you can use tps to control idle from the sentence above. I talk to Steve about it.

Hey, Where was it that you said you got the pistons you sold me? Were they from Corksport?

They were originally from SR motorsports listed at 10.7 but the part #s equate to 10.4. They look the sames as the 10.4 i kept from Corksport.

Update!
P&P head and other misc goodies from PG shipped today! I should see them early next week. Will have pictures up very soon after getting the parts.
