    Hmmmm....
    Maybe I am suspicious by nature, but personally I would not put blind faith in the chip manufacturer (nor Toyota for that matter) to safeguard my "enhanced" donk unless they could tell me EXACTLY how the chip modifies the fuelling/timing, and guarantee it. Steinbauers are allegedly one of the best and are said to have all the built in safeguards, but we are now seeing 1KD's grenading, even with the new injectors fitted. The CF34 turbofans on the company bus have dual channel digital FADEC engine control, but the manufacturer still requires all the gauges to be operational for me to continue operating them. EGT and boost gauges are cheap insurance: knowledge is power, ignorance can be expensive bliss.

      Not sure on the Steinbauer chip. Unless its changed in the last 18 months. It was a one chip fits all and it just boosted fuel rail pressure. Plug and play no live dyno tune. Hopefully they have changed.

        The Steinbauer does not change rail pressure, it only adjusts fuel delivery timings. Hence it doesn't give the same power/torque results as a lot of the other chips that adjust rail and turbo parameters. Apparently it also progressively drops settings over 30 seconds as a safety measure.

          Correct gauges you can see are cheap insurance

          just because unichip can regulate its parameters from factory sensor does not guarantee it will effectively lower them or that the computer will throw an engine light for that matter if the chip has issues

          My last unichip had a " factory " tune setup on map selector no.1 but the chip had issues so did the so called " factory " tune as it is still running that tune through a chip that had issues. Fairly well convinced my gauges saved me a motor and a very $ being a 1vd

          Boost was spiking upto 26psi off idle, has a factory limit and a unichip limit of 22 ? Neither stopped it over boosting to 26 psi. Or alerted me to any issues

            .....and yet we seem to have a couple of 1KD's with Steinbauers that have detonated.

              Quite plausible if the problem is the piston, but curious about the facts to support this.

                I'll stand corrected.

                  Unfortunately, without the data (boost,egt,coolant temp etc) we will never know. From my sample of one, 14.5psi boost cracked the head, but the pistons survived (1KZ). So I deduced that too much boost is Baaaad, M'kay?
                  The only way to get a handle on the problem is to have some reliable data. If you don't have the data, I just can't see how you can safely set/operate your chipped engine. You may dyno the thing, but an engine dynoed to the max output at 8c and 1023Hpa in Melbourne in the dead of winter is going to be a different animal in the Kimberleys at 45c and 1005Hpa in the stinkin buildup in Oct. I have run mine over widely ranging conditions, from Falls Creek in June to NW Oz in October, and I have been regularly surprised at the boost/egt/coolant temps I have seen.

                  Everyone can make their own choice, just be sure to let us know how you get on!

                    One cool thing about the Unichip is that you have the ability to choose the tune be it more economy, better for towing etc. So if the temps etc are adversely high say in the Kimberley 45deg then it would make sense to use a lower setting that does not stress the engine and over heat components.

                    Thanks

                      Agreed, but how do you know how much to tune it down? Operating without the gauges is like driving around without a speedo, even your best guess may(will?) sooner or later cost you $$$$.
                      There are too many variables (temp, boost, load, ambient conditions) that you can't accurately predict when the limits are being reached unless you have the data.

                      Sorry, I am starting to preach, but I hate to hear about engines blowing when you could lower the risk.
                      Maybe I should just shut up :-)

                        Scangauge II or OBDII bluetooth with Torque Pro or similar and problem solved. Even without tuning the vehicle they are great for towing to watch the Auto temp etc.

                          As long as they give you EGT, boost is useful also. I didn't think these gauges read that data, but I could be mistaken?

                              Yeah i can confirm too.
                              Mine reads boost, egt, dpf, water temp and all the ohter normals

                                My understanding is the chip intercepts the information changes it prior to being received by the ECU ?
                                So I'd imagin an OBD reader would be no good for some of those readings like boost and rail pressure ect.

                                Not too sure about ETs they are read around the DPF ?
                                You really want one in the manifold prior to any boost dumping through the wastegate for tuning perpouses

                                Sensors and gauges independent of factory system are the go.
