Happy Bday mate

From my experience, the initial purchase price is similar when comparing dyno's with similar features, I have been told that DD are expensive to update once purchased. Mainline seem to be popular amongst users that look for information rather than just a machine that can do a dyno run.

Removing your cat and not replacing it or gutting it can lead to a huge fine, there are plenty of aftermarket items that will flow plenty of power

From what I gather, it appears that it was bought out by a larger company, not sure what time period though and now that company has decided to close it down and put it in the hands of an administrator, hopefully some body may save DD

Have been reading on several other forums that Dyno Dynamics have closed up Caplink Corporate - Advisors on Business Sales, Mergers and AcquisitionsCaplink Corporate - Advisors on Business Sales, Mergers and Acquisitions Closure report Not good for our industry, possibly some of their dyno users may be able to shed some light on this

You've been told some lies and yes your box can still be used if your tuner is currently registered. This is assuming the box is not vin locked to somebody elses car

Unless you have it emission tested, it is considered illegal as it has changed from manufactured.

technically, a tune is illegal. A decent cooler is probably the best thing you can do for your turbo followed closely by a decent exhaust system

there are more important thing rather than air fuel ratios that make a tune "safe" if you want safe, leave it stock

Before buying anything, check to make sure the flapper is actually still connected to the actuator arm, if it has come off (unclipped itself) it could be holding open allowing exhaust gas to pass and causing slow boost, I have similar slow boost in a car that had a jammed flapper.

There goes my idea then

has your turbo been ported?

Too many things that can affect economy to list, but main one to remember is the car follows the petrol operation, if there was an inherent problem with the ecu for example to problem will flow over to the gas as the gas does not use it's own ecu, it uses the cars ecu. Are you oxygen sensors good? How old are your plugs? Is your air filter clean? Another thing to consider is how the installer has placed the injectors etc, if not straight it could be spraying gas onto the wall of the inlet runners etc which will affect burn etc. Have your driving habits changed now that you have a cheaper fuel source, ie accelerating harder more often, so many people do this after installs as their car is cheaper to run.

we saw 350 rwkw in worms car, but the system was modified from standard.

It was explained to me many years ago, that in Vic, the speed zone does infact start as if there was a line across the road at the speed sign, it may have changed by now.

Not me mate, my plates have been on since new

If your talking about Nath, he was down a little and only ran 10.0 @147 mph

85 litre tank in my ute and it fills normally 67-69 litres. A liquid tank will refill slightly less than an equivalent vapour tank due to the space taken up by the fuel pump and also it will switch back to petrol while still leaving a bit of liquid in the tank to save any pump damage.

I have heard that Air Power Systems (APS) came with emission approval but do not know whether this is true or not.

Never had one done but think it is something like $8000 a time for a lab bag test (not im240) and if you don't pass you still pay the full amount next time. Not trying to sound like an add, but we have changed 1 car (a poster in this thread) to complete Nizpro gear, fitted a stock exhaust system, tuned it to meet the testers requirements and had the car passed through first time. This test was for a EPA letter received in the mail and not a lab test. This was possible because presenting the car using complete Nizpro gear was acceptable because Nizpro had a car tested in the emission labs and can now supply paper work showing their kits will meet emission levels

Altering a cars tune can affect the emission levels the car will produce, so it is deemed illegal unless you pay to have your tune tested at the EPA emmission labs.

Once the tuner has a collection of tunes, he should have something that may be close to what will work in the car, but would probably pull some timing out accross the board and richen it up a bit to allow for any operating differences between different cars. Once it is determined the car is safe, they can then set about getting correct boost and air fuel ratios and when satisfied start to chase spark timing. To do it correctly rather than just chase an outright dyno figure, timing will have to be changed at each load and rpm point to make sure the customer is receiving the best power tune available. To determine whether the maximum has been acheived they will have to go past the best spark point to where the car would drop power at the rpm point they are looking at. When it has gone past it, then the timing can be pulled back to where the maximum was. This has to be done 1 rpm point at a time so as not to get false readings. This is what takes time to do correctly. Then every time spark is changed, it can affect boost slightly so that has to be corrected and possibly air fuel tables. There is also things like getting fuel trims close to zero at idle etc to help correct starting and running etc before closed loop is achieved. Then knock sensors need to be turned on and recheck for any false knock and correct if needed. Finally the car needs to be driven on the road to check operation in the real world and things like auto settings can be tailored to suit the owner. This is assuming the car has no problems like torque management issues, coils breaking down, owner induced problems like boost pipes blowing off and having to be rectified, sensors not fitted at all, camshafts not fitted correctlty etc, beleive me I see it all the time This is just a quick run down and some tuners will do it differently to this.

The early flash box's take approx 2 minutes to load a tune from the laptop and then a BA will take approx 4 minutes to load from the flash box to the cars ecu. It may take 15 minutes between runs due to time to do a dyno run, analyze what is what, make changes in the software and then do the file transfer process. This is why I have concerns about some members believeing they have a full custom tune and it was done in an hour.

Give us a call tomorrow and we shall see how we can help you out.

Christian, we have seen 1 walbro fail and it was seperated by the supplier and found to have foreign matter in it and was not covered because of this, we have also seen several others that were blamed on the pump and when dismantled found the owner had used normal fuel hose rather than submersible hose and the hose had split. Suppliers will normally only give you a replacement pump as compensation if the pump has been deemed as warranty.
