Kudos to the Skyline owner on the unique build. Pretty impressive figures given what he built it with.

Hey Mao,

EMPTY YOUR INBOX

Can you PM me a price on the Cobb Access-Port for the MPS.

Daniel.

Hey Mao, very impressed with Warwick and your efforts with tuning my sg9 foz xt and installing the STDs. I am very happy with the results of the tune, and the car is worlds apart from what it was, given its an auto. I'm now thinking it may be worth turning up the boost to maybe 1.2bar!

Cheers adrian

Glad that the Forester is running great. hahaha it is normal to want more and I myself would want more boost too.

The vehicle was running too rich and boost was set at 0.88bar when it came in.

Warick reset the AFRs and increased the boost to 0.95 bar and it made 30hp more.

Yup 1.2 bar should make a bigger statement.

Below was your before and after dyno results.

Apexi Power FC tune on GC8.


Vehicle came in with a misfire right after 4500rpm. History of this GC8 was that it belonged to a place called S2R. Have no idea where it was tuned before but detonation was picked up on the Dyno logs on the first power run.

The previous tune in the PFC was so bad that detonation melted the tip of the plug, causing the misfire.

Plug with melted off tip:


Look at the boost spike to over 1.7bar due to the detonation. This problem was fixed after we corrected the ign timing in the PFC, with new NGK Iriway 7 Spark Plugs and NGK Ignition Leads.


NGK Ignition Leads installed (blue in color):


Apexi Power FC tune with Process West intercooler and VF34 boosting @1.35bar。 Power was brought back up above 260hp and 330Nm. The injectors were maxed out at this point.

Car feels awsome after the tune this morning. Thanks again.

The pleasure was all ours dude. Glad you can feel the big difference in driveabilty and it is not just about how big the number is on paper.

We have been doing quite a few flash tunes on the WRX's and Foresters with the Automatic transmission.

Below is a recent retune of sf5gyauto's SG Forester. You can see the previous tune here:

Anyhow, he wanted to see if we could improve the tune with more than 1 bar of boost.
Results are below. Boost was increased to 1.25bar and tappered down to 1.0bar from 5000rpm to 6200rpm:


P/S: Just in case anyone asks about the Torque graph, Answer: Automatic transmission torque converter.

Today's tune on MY06 STi.



This vehicle has had a prior tune done elsewhere and we were given the job to freshen it up.

This vehicle came in with a Spec C Twin scroll turbine setup, including Spec C headers and upipe. However, upon close examination at the last service, we found the headers to be leaking slightly, while the STi was very sluggish.

Once the leaks were repaired, Warick proceeded with the power run. Vehicle also had a slight misfire. AFRs were too lean as well. Once again, the AFM and spark plugs were the problem.

Note color of spark plug --- vehicle has been running too lean:


Below is a pic of the cracked insulator on the spark plug, caused by overtightening of the plug.


These were replaced by the JDM NGK Irimax Spark Plugs Evolution R stocks for the 2.5 boxers.
