Milli Volt readings

[Mr.Spool]

We didn't have Grand Nationals before Jimmy Carter put ethanol in gasoline.

sunoco 94 to my knowledge didnt have ethanol we ran mainly straight gas up here.

 

[Mr.Spool]

Thank you Mr.Spool

your welcome

It may be worth investing in a wideband? My stock o2 is way off compared to the wideband readings. I got an AEM uego for under $200.

How does those work ? I may be showing my ignorance

Kinda what the name implies. It is a much wider swath of info. More info can give you the data you need to make good tuning decisions.

Usually mounted in the downpipe, they don't replace the stock narrow band unit. Need a welded in bung to mount them in.

If this is the car and running 16 psi manifold pressure, one of the first things I would do, is install a stock turbo. It will be much quicker on the street.

It's a more modern, accurate sensor similar to what new cars have. The sensor is installed in the downpipes with an included bung. The wire from the sensor goes to the gauge inside the car, which wires up like a relay. I have mine mounted on the steering column, and check it periodically to make sure the car is running properly.

Just asking but why do you think a stock turbo would be better ?

Much quicker spool up resulting in much quicker 60'. The 49 is not making any more power for you at that pressure. It's only slowing the car down.

No need for a bigger turbo until you start running greater than 21-22 psi manifold pressure. At that time, you need start thinking about a converter and transmission shift kit or upgrade.

The car has been very slugish starting off and I did wonder that . I have thought about alky in the future but the tranny is stock and so is the converter .

Verify you have no exhaust leaks.

 

[TurboBuRick]

Yes. Check for pre turbo exhaust leaks. They are like a open wastegate. Also, check the wastegate. Make sure the puck is in tack and sealing.
