Hey guys,

Well I just got my car back from RE Customs the other day and its making 280 rwkw on 16 psi (I run it on 14 daily). Last night I decided to try my high boost. the car takes off and then gate opens blah blah blah, BUT then as its getting to around 4 to 5 grand (was too busy focusing on the road) I notice the engine light flicks on and off, the flicking was similar to what happens when a light has a loose connection and whenever it moves, for that split second the connection is good again it lights up then dies again. Don’t get me wrong, I don’t think it’s a loose connection, imp just wondering what may be hurting my car. the car is stock internally with all the usual mods to support a bigger turbo (management, fuel system, exhaust, intake, afm etc) so I thought id come to the brains trust and see if you guys have any thoughts on it.

Cheers,

Ryan

hey mate

Sounds to me that the car is doing one of a few things

1: Knocking

2: maxing the AFM

3: maxing the injectors.

Can you do it again and this time get this data from your ECU's hand controller

1: the max knock level

2: the max injectory duty

3: the max Air flow meter voltage

then we can determin what the issue is. Is the flashing very fast or is it slow?

cheers

Hey guys, whoa you work fast! Well the light flashed sporadically, and at a fast rate.

DAMMIT! I was hoping it wasnt knock as I mulled over it last night but given what you just said Guilt I think its knock. Im running 550cc injectors and a Q45 AFM so there shouldnt be any issues there.

I actually dont have a hand controller for the PFC as I got it as a reiculously cheap price (before they ended) minus HC. Iv been looking at getting one but I was addressing othe areas of the car before hand as i heard they went that necessary.

Thanks for the quick help boys, if you have any more advice just shoot away, last thing i want to do is melt an engine.

Cheers,

Ryan

tell your tuner to come for a spin with you and show him the problem. Sounds like they squeezed it a bit hard and it needs more fuel or less timing. They should fix it up for you on the dyno for free since you paid for a full tune.

If it was engine noise, you would see warning lights on low boost also, probly knock warning....

what i meant was the light is probably triggered by the knock sensor, but the knock sensor may be picking up a noise caused by something else rather than detonation. it may just be loud enough at high rpm for the knock sensor to register it. it is more than likely knock, but there is always the chance it is a false knock.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
