Re: 1st Start-up video on Page 33!!! - Speedfoos' Turbo Install
Ok honestly i am now just catching up to this holy grail of a thread. Why was it surging so much on the first start up. You said it was missfiring. What codes are you throwing. If you are using the xfc base map i built then you need to make sure that the wideband signal 5volt is being sent to the XFC.
Also send me a datalog of it idleing and I can see what is going on.

MMMM Alpha i have a piggy back system and I put down 205whp and have never had my car in the shop since day one of my turbo install. Its not the systems its the tuners that tune the system. A good tuner will never let a car off the dyno unless the A/F ratio is flatlined across the rpm range.
Good tuners are not cheap cause a dyno jet cost 43grand then add on the cost of all types of tuning software and you can have 60grand tied up like we do here at the shop

Hey buds, the only thing is that it shouldn't be dumping a lot of fuel at idle. The target AFR is set to stoich for idle so technically it should be running like normal until I start giving it gas and load, right? Or is this the beginning of a lot of headaches with a piggyback?
Any of you PCS owners out there? How's your idle AFRs?
I'm gonna play with some things tonight. Like I said, what's most worrysome to me is the fact that my ODB scanner won't interface - both with and without the piggyback plugged in - and my tach doens't work. Another question. If I just plug the stock ECU back in (no piggyback) to check tach and OBD, and start it, will I potentially fuck things up? This will be with stock injectors and no revving.
Off to work now. Thanks a lot folks, keep it coming.
OK at idle you should be at 15.2 to 14.2 range. Also if your ODB2 port does not work you need check the fuse to the cig lighter. They are tied in together. So make sure that there is nothing tied into the cig lighter. Make sure you have the XFC hooked up right. If it is running rich and throwing map codes you do not have it powered up right. Look at the fuse to the XFC make sure its a 25amp fuse.

i hate to be rude, but you mention that ypou never had your car in a shop since day one, but you later credit yourself for a 60K dyno that your shop has, therfpre you claim your car has BEEN in the shop...sory

OK, no pissing contests guys.
Chris, I'll be giving you a ring later after I sort out the things you suggested. Ah piss on it, I'll give you a ring here directly because that's easier.
Good call on the cig lighter fuse. I'll check it, but I have nothing tied in off of it. PCS powers up correctly and is able to datalog. I'll send you an idle datalog here in a about 30 mins as soon as I change the plugs and the injectors back out. PCS has the 25 amp fuse attached and its not blown. I get good comms between the laptop and the unit.

Re: 1st Start-up video on Page 33!!! - Speedfoos' Turbo Install
All right. Just got off the phone with Chris and I'm ready to fix this thing. I also brought home a MIG welder today to learn how to weld this weekend and fix my exhaust.
Back in a bit.

OK being technical about it of course it was in the shop to tune it. I do not have a dyno at my house. I know dynos are common at houses but i decided to go with a pool insted of a dyno at my house...
Re: 1st Start-up video on Page 33!!! - Speedfoos' Turbo Install
LOL - I haven't been to the gym in months prior to this week! My buddy and are back at it though. This was "The Summer of Sloth" for both of us!
OBD and datalogging are two different things. Datalogging is a function of the PCS which takes all the readings from the unit which interfaces with the PCS software on my laptop. The ODB port, down by the gas peddle, is where you plug in a scanner to read and clear DTC codes to get rid of the Check Engine Light.
Video of 4th start-up is recoding and will be uploaded soon. Chris has my datalog and basemap to start troubleshooting.

Re: 1st Start-up video on Page 33!!! - Speedfoos' Turbo Install
Processing on YouTube right now. It's uploaded and is grinding away on their server for whatever format they use.
Problem appears to be because my ECU is not receiving an RPM signal anymore. Pulled the PCS out and started it with just the stock ECU. Still no tach, which means neither the ECU nor the PCS can figure when to flick a spark and do other important technical engine things.
