SD2 with IAT in the intake tuning "AROUND"?

[greeneyegi]

so ive replaced the engine wiring harness with a caspers.added AEM 3.5 map into intake manifold.also tapped the iat in the intake.what steps do we take to tune alky with the temp sensor in intake instead of before alky .
i heard the term tune around this somewhere.

If you had it tuned with the IAT before the alky nozzle, and then you moved it to after-alky, the temperature will read colder now when spraying, so it will get richer. You'll have to decrease fuel a little bit in those areas of the tune when the alky is spraying. You will see it in the correction as long as you are running closed loop.

since ordering the chip ive added rjc front mount would that have any changes on the tune you would have burned ?

No, the base tune is the same.

so is the wb still giving me a true reading of af?its just the iat thats a false reading?sorry,it takes a brick upside the head to understand this stuff sometimes.

Everything will read fine. It will just be a little richer than before, so you'll have to lean it out.
