I just recorded some clips with one of my EGT's going crazy if anyone wants to see it. I think its quite amusing to watch. I need a host for it though.

I just wanted everyone to know that HKS is showing good customer service as their manager of R&D HKS USA just emailed me wanting to help me tune my system.

i tapped my EGT sensor into the left manifold if you are facing the motor from the front. EGT reads on my greddy gauge up to 7.5 ext which is normal for 7lbs of boost

If I do get my sensors moved, I might as well replace the cats with my stockers since they're the main cause of the lean afr. However, I did notice that after I got the tp's I dont scrape bumps anymore.

Any Idea on the spastic EGT?
Well if you want it to be of any use you need to have it about two inches from the block to be accurate, right now it is useless to you. The problem is that the headers will have to come out unless they have magic fingers and can get it done with the headers in place, doubtful, at which point might as well change to test pipes. Is your wideband sensor before or after the cat, I can't recall if you said but can't go read while I am responding.

The spastic EGT is probably due to the fact that it is so far away and by the time the exhaust gases get to it they are turbulent causing the changes in temp reading.

Umm. My mileage has been about the same. Obviously the aux injectors only come into use at higher rpm so unless you are driving hard everywhere the mileage should be around the same.

pumped, I replied to his original email but haven't sent any others.

mr rizk, i put in 10 gallons from empty 2 days ago(half tank) and I only drive at most 20miles a day, thats just to school, to practice and home. and i'm already at a quarter tank. that would be less than 10mpg.

Okay stupid question. What is your AF ratio like. What I mean is maybe one of the injectors are faulty or there is a leak under pressure in the fuel system.

Just a thought

PS: I get around 6.8 Km/Litre which I think is about 15.9 mpg

Last thought. Do you drive with the air con on most of the time. I have noticed that mpg does reduce by at least 15%

Dlin05,
I am the one who emailed you. I did not receive a reply from you, possibly because it was filtered out. I have been getting alot of junk mail so the spam filters have been increased.
If you can please resend your reply to me, or send to my other address - jon@fastraxturbo.net

haveing 0 problems with mine I just dont like it when I am highway driving and shift to 4th to pass seems I loose power and soon as I hit 5th Its pulling again. think its because of where my rpm,s are at because the HKS starts to loose boost at 5500 but shifting to 5th at 80mph my rpms drop to around 3k and power is great there. thats why I am adding some JWT cams but anybody running or thinking about running this unit I would get the v pro makes a world of diffrence

He is referring to the FCON V Pro. This unit is required if running a modded Z with the HKS SC. Since this kit is untunable from the factory, adding the FCON Pro allows full tunability I believe. I believe its just a piggyback ECU or something like that.
