One more thing- I am not sure about the Series I, but series II 3800 do not have a distributor gear on the camshaft.

I bet, that a carbureted 3.8 will make less than 205HP, which is the 2003 PT Cruiser Turbo. So IMHO, swap in a turbo motor from a PT and you will be all set. Later, you can upgrade your injectors,...

Well, there is a company out there that makes a "piggyback" voltage booster that plugs into the alternator and artificially increases the voltage. It would be nice, if we could do this via software,...

Is your fuel pump stock? I had the same problem with 42.5# injectors and though it was losing only 5PSI FP at WOT, it was enough to choke it.

Mototron 65lb. I will try and add more fuel to see what happens.

Just to bring it to your attention, I posted some details. What do you think?

I'm sorry. I should have given more detail. Its a L67 with MP112 blower(17 PSI from 2.8" pulley), AC intercooler, LS1 MAF, LT1 TB, INTENSE 1X cam, P&P heads, SLP headers.
I don't hear any...

I need a experienced opinion on my KR. Can someone please evaluate my scan and tell me if this looks like false knock or is this the way REAL knock looks. The car was loosing traction off and on due...

Can someone please explain how can I get the air-fuel ratio( even though in rough numbers) from the O2 sensor voltage? :huh2:

Thanks, John! I guess I will need 50lb injectors :banghead: or I can try to lean her out for now. I have another question- how can you pull out the AFR from the O2 voltage, even though it would be...

OK, anyone on Pulse Width Modulation for our PCMs? Does it change or is it a constant value?

Can someone enilghten me on injector duty cycle? From my last log I see that my injectors reach 24ms and I don't know what % this is. Is there a way to calculate the duty cycle from the time they...

I'm sorry. I got lost. :-[ What do I do now? :banghead: HELP!

Sorry, I thought all DTC's are the same for all PCM's. Didn't mean to offend anyone, just trying to get that problem solved :banghead: .My PCM is a 1998 GTP.

Wrong! 1665 is "driver 3 line 5" and 1676 is "driver 4 line 6". Is that the injector drivers?

I am having a problem with a DTC. First it was a 1665 and the description was "driver 3 line 5" and recently I got another one with description "driver 4 line 6". What is this? I can't find any...

Its 9352809.

My intercooler is now ready and my email is screwed up- I can read messages, but cannot compose and send any. Let me know what kind of testing I can do for you and if you can send me an update.

I also have another question(maybe you will have to move this one). I hear people talk about the 3 bar GM MAP sensors and I know that my motor i equipped with a 2 bar MAP. My MP112 blower makes about...

I am running my GTP motor with a custom made intercooler that uses a 2" thick heater core under the blower and a aluminum tank that encases the AC evaporator. The tank is filled with antifreeze and a...

Yep, that's my misundersanding. I didn't know about the sprocket's ratio. Thanks!
I also have another question- I have raplaced my MAF sensor with a LS1 unit. From a website called www.LS1HOWTO.com...

Okay, the car is a 1996 Oldsmobile Cutlass Supreme with a 1999 Buick Regal engine(3800 SC) and the wiring harness is a 1998 Buick Park Ave-to original firewall-to 1998 Pontiac Grand Prix GTP PCM. My...

I have a 1998 4T65E-HD in my car and when I wanted to change the tire size, I noticed that the calculated gear ratio was set at 3.29 instead of 2.92. Now my speedo is incorect (shows higher speed)....
