Title says it all, almost. My car starts first time immediately when it's cold. When it's hot it cranks for a lot longer. Too long. I have tried adding and removing fuel from the cranking setup. A tuner I spoke to told me to watch what cell it is using when I turn the key and add heaps of fuel there. There is as much fuel as I can add in the first 4 cells of the fuel map and no better. I haven't changed the voltage on the fuel pump yet. Ideas?

Mine is does it consistently. Could it be because of having 9xxcc injectors? The latency time is not far from stock. 0.58ms Although it does start fine every time when its cold. Could it be coils? Most of the time it starts with a miss for about 2 seconds. There are new properly gapped plugs in it.

Cos I have to let the O2 sensor warm up I tried something different. I let it warm up on accessories and then when its ready I turn the key to on. then start the car halfway through the prime and it starts first time. It must have been losing pressure in the rail cos it primed then didn't get started till the sensor was warm 15 seconds later.

Are u talking about the wideband? U dont have to let

It warm up. Start the car then plug it in.

It says in the instructions to turn on the power to the wideband and when the light stops flashing to start it. This is to let the heater in the sensor warm up and stop the sensor getting clogged with soot. They say it prolongs sensor life. Everything about the wideband gauge is soldered in. There is no plugging in. Have a look in the wideband thread. I put a clip in there explaining about how it works.

    • 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.
