z1 intake manifold and tuning??
 

so guys z1 says their intake mani requires a tune but does that mean i cant drive like 40 miles maybe 50 min without one...i wanna install myself to save money and then drive to the dyno destination

The increase in airflow is prominent in the extreme upper rpms. Drive it like a grandma (low rpm, low throttle) to the dyno, and you will be fine.

it wont matter much because the oxygen sensor are still doing their job and will correct your AFR to be where its suppose to be in closed loop ( idle / light cruising )

and then in Open loop (like 30%-100% engine load) your MAF are still doing their job by calculating the air flow going in. So it doesn't matter if you change you intake manifold for another one.

The difference in AFR wont be very much different after the intake manifold swap. only by a couple tenth of AFR. because the load rating will be moved into other cells.

Unless you were already running very lean at WOT. I wouldn't worry if I was you. the system can adjust up to 25% more or less fuel than stock form.

but I would also recommend doing a tune to extract the most you can and there isn't any need to drive it like an old lady.

I would be interested in seeing what you make WHP if and when you get a tune, I went the other way( some advice on here to go M370).. I'm still waiting to get to the dyno on the 11th next next month.

:iagree:

I did the grandma driving for about 100 miles, just to make sure the car had adjusted, then drove normally without a tune for about a month, then finally made the trip to Z1 for a tune. I had no issues during the time that I was "tuneless."

Did you post your numbers somewhere? Looking for some comparison to my Motordyne , We have similar mods. They dynos wont line up but do to see something I can take with a grain of salt:tup:
Only issue I ran in to was a small leak at my MAP sensor( but mine is different for the Motordyne) Ran over timing advance and random misfire. but both were my fault :/

ok and no codes came up on the OBDII reader after install with no tune right

You Shouldn't see any CEL light unless you didn't install something right . I installed my M370 and been CEL free for about a month . Ex the mistake I made with a vacuum line :/

whatd u do forget to tighten something

you should be fine I installed mine and drove for a few days before I got tuned. car has that r2c intakes, ark high flow cats and ark catback system. made 313whp and 265tq

I did, LOL or not enough The rear vacuum lines for the MAP sensor were leaking in air and threw a CEL , :/
