General Buick Tech / Did I fry my ECM

« on: April 16 2012, 10:26:10 PM »

Installed turbo tweak chip today( motor hasn't been started yet). Everything seemed good. Ses light blinked once then sayed on, scan master came on and went into waiting mode. Turned the key on and off a couple times everything seemed good. Went to tuck ECM back into it spot and the orange power wire pulled out.i got the wire securely back into the plug and checked to make sure I had 12 volts to the pin connector but the ses light will not come on. The powers there but no ses light. I'm thinking I fried it. Can get my hands on another gn ECM but not till this weekend. Hoping it's something stupid. Any ideas?

Transmissions / Good converter for my set up????

« on: April 04 2012, 08:32:15 PM »

When my transmission was rebuilt I ended up with a 1900 stall converter based on the recommendation of the tranny guy. I'm now thinking its a bad match(wish I had done more research). Should I just be going with the stock d5 converter or a higher stall, lock up, non lock up. I don't really know my asshole from my elbow with converters so any help will be appreciated


Stock turbo
Stock down pipe
Adjustable waste gate
High flow cat & cat-back exhaust
Comp cam 260h
Roller rockers
Port & polished heads
Stock intercooler


Hope thats enough info I don't have all the receipts on motor & transmission build with me right now.


I want to order a turbo tweak chip and 60 lb/hr injectors but don't know which Converter I should put in the my set up part of the order. When car is running it will be going to transmission shop to be adjusted and if the converter I hav is a bad match I will order a better one now and have it changed while there.
Thank you

General Buick Tech / Getting ready to start new motor

« on: April 03 2012, 11:40:56 PM »

First off I'd like to say hello and a thank you at the same time. This site has answered several question already for me utilizing the search function.


A quick rundown.


I've had my Gn since 2003, I got the car as a high school graduation present. In late 2007 I blew a head gasket. The car had 121,000 on it. I was running a fresh turbo, a set of headers, high flow cat, cat back exhaust, stock injectors and chip. Car was running really good minus the transmission that was on its way out. Probably should have fixed the head gasket and put a new tranny in it but hindsights 20/20 so out it came to be rebuilt


New combo
Forged steel crank
Eagle rods
Je pistons
Flat-tappet Comp cam(can't remember exact grind. 1 step above factory as I still have stock chip)
Roller rockers
Balanced & Blueprinted
Fresh rebuilt transmission with shift kit


Motor has been done since 09 but sat in the car about 3/4 done as I played with my other car and bike for the past couple years. I will be starting the car Monday if all goes as planned. I've done the following over the last 3 months since beginning to work on the old girl again.


All new Vaccum lines and check valves(zip tied everywhere)
All new heater,coolant & radiator hoses
New radiator(utilizing stock oil cooler)
B&M trans cooler with braided lines
New oil cooler lines
Converted to Vaccum brakes(powermaster was toast)
Reprimed motor(read 60 psi on gauge)
Set camshaft sensor with the tool
Installed scamaster 2.1, vdo boost gauge and an auto meter tach(already had oil & temp)
I have rotella 15/40 with zinc additive for break in oil(what the engine builder put in)
I have put in 5 qts of tranny fluid to start


I think I'm good to go for start up and break in(will be doing it with the engine builder)
Anything I'm forgetting or overlooking?
Sorry for the long post
