Has anyone ever had any problem with the wiring loom and computer plug on R32 RB20's? I'm asking this, because dispite putting in a set of split fire coils, new plugs (0.8 gap) and tying a different ignitor, my car (S13 Silvia) has a BASTARD of a flat spot. It's going to be hard to explain, but here go's. It idles fine. Drive out the drive way and it feels abit lifeless. Drive down the road and it lacks response. Lean on the throttle (not full throttle BTW) and it feels like you've put your foot on the brake at the same time, despite the boost gague showing 3-5 psi. Hold that throttle possition and when it gets past 4200rpm, it gets a new lease of life and takes off as you'd expect. Get past 5000rpm and it go's dead and struggles. Sometimes using less throttle can make the car feel faster.

Car has a new fuel pump (Bosch 040), runs OK air/fuel ratio's (11.5-10.5:1 under load/boost), I've cleaned the airflow meter (R32 airfilter box/standard throw away filter), base timing is 15 degrees.

It hasn't always had this lovely feature, and it has come and gone befor. :yes:

    • Just wanted to share the recent dyno results on my car. 20lbs of boost on pump gas. Pulled the fuse on the AWD so it was only rear wheels on the dyno. It made 484 hp at the wheels. I asked the tuner to see if we could do something so it breaks the 500hp level, but he said that we were maxxed out on pump gas. If i wanted to make more power, id have to go to E85.  7f8604df-f686-466f-b2ec-e1d8a369ddd9.mov    
    • While there is no current law for the spoon, let's swap to a different utensil. Example, does the store get fined for selling a butter knife if it ends up being a murder weapon? Perhaps they cpuld be done for assisting if they *knew* it was going to be for such a purpose. But, if used properly, which was its primary design, it's a tool for a job that's legal. I could understand companies being prosecuted if they advertise their products for being road legal if they in fact, are not. Possibly, but not necessarily, the tuners for tuning a car to a non legal fashion(emissions), but there is always the possibility that the customer really doesn't intend to use the car, in that configuration, on the road. So long as the companies can prove they have conveyed how illegal it is to use the now illegal car, in a place where the vehicle must meet the laws, they shouldn't be punished. Not sure about other countries or states, but I've been made aware that I can't legally stop a client from taking and driving their own car in NSW, Australia, even if they owe the shop money. It must go through court to get the funds from the customer, and you need to get the police or roads covering body representatives to come and stop the owner from driving the car, even if I know how hazardous the vehicle is.
    • probably around the $1700-1800 fitted in his sizes.  The ar1 is heaps cheaper. Get on scumplace I got some A052 295/35/18 for $400 that had done maybe 20-25 hot laps of SMP. 
    • People are going faster on CRS than AR1, so there's that 😕
    • Go the CRS, cheaper than the A052 and same if not better 1 lap performance when suspension is dialled for it. If wanting to do back to back laps the A052 and can cool off and go again next lap will be the better option. I have gone quicker over 1 lap with CRS than the A050 I came from but may be due to getting more seat time. I am driving CRS on the street lately in different conditions and its going well, a lot better than AR1 in the wet. AR1 is a race tyre, CRS is a Hill Climb/time attack/Sprint tyre. 2 different things, a slick is on the way too. The mighty gay mods choice of tyre is proper rubbish for those that actually drive on track not park at bunnings at night.
