      Engine Issue

      Resizing injectors in Nistune can be done a couple of ways, and there are a couple of ways that you can make a mess of it. The tuner needs to be really aware of the effects of whichever approach he uses (either K, or TIM). They are both easy enough to "get the injector size right" to run the engine. But little details like old start enrichment and hot start are affected differently, depending on which boxes you check.

      Pretty safe to say almost everyone that has tuned their own car has experienced this issue. The difference being that we have our laptop in the car and when it happens, it's literally 10 seconds of tuning to sort it.  Would you be happy to plug in your laptop and sort this yourself? It is a very simple process and there is no risk of harming your engine (if you are worried about that).

      Basically your tuner needs to drive it for the 30 min (or whatever) to create the same conditions then check the ECU settings and sensors at that time. They may not be excited to because that takes them 30 min rather than just opening the bonnet and seeing the problem straight away.... Hot start is generally not as tricky as cold start, but there would be a table for fuel enrichment vs coolant temp as a starting point

      Yeah, they all cant say anything for sure as everything is working fine . Said unable to find an issue untill it stops again. Could mist likely be CAS wiring or IAS valve issue but again not 100%
