Even better, you can easily do something better than that, like what my unit does (detailed in later posts).<br /><br />The unit operates based on input voltage, so xE will stop at ~4.2V, x7 will stop at 5V. Similarly 8x will increase the output voltage by ~9%, Fx by ~17% and you can extrapolate any values from that, which is what they do anyway.Ligiushttps://www.blogger.com/profile/04631687424641789584noreply@blogger.comtag:blogger.com,1999:blog-6053337542597571017.post-65909164039879692602021-10-10T13:37:55.630+02:002021-10-10T13:37:55.630+02:00Very informative articles.

In your case, you mentioned that X8 was at 30% load will cease intervention, X0 at 60% and X7 at 100%. Can you please complete all the diagram starting from X8 up to X7 with 1 increment only. Example: X8 = 30%, X9 = ?, XA = ? and so forth. Thank you so much and keep up the good work!!

The most likely reason to do so is to avoid the "check engine" light in case of high loads, e.g. pedal-to-the-metal from a low speed in a high gear. Can also happen while uphill, engine is cold, etc.<br /><br />If you do get the check engine light but still want to keep the RPM range high, you need to decrease the first encoder.<br /><br />Another way to handle this is to keep the RPM range low, in case you want only low-RPM torque and keep increasing the first encoder until you get engine errors, then dial it down.<br /><br />To put it in more technical terms, the ECU will likely give out an error if the signal is higher than 4.5-5V, depending on the car, which the "tuning" unit above is able to do, depending on the switch settings.Ligiushttps://www.blogger.com/profile/04631687424641789584noreply@blogger.comtag:blogger.com,1999:blog-6053337542597571017.post-55865536904382887022018-10-18T06:23:56.462+02:002018-10-18T06:23:56.462+02:00Thank you so much for this post, it really helped ...Thank you so much for this post, it really helped me to understand how my RaceChip works. I have a question that I hope you can help me with: What would be a good case scenario in where shifting up or down the second rotary control might be a good idea? As per your explanation, it will set the RPM "working window" in where the chip is meant to work, so past this value it will revert itself to "factory settings" until the RPMs are back in track. As there is no minimum value for this (idle in your case), do shifting up the second control just expands the RPM range instead of moving up like the steps in a ladder? Why would I ever want to move the secondary control from the default? That is something that is not even mentioned in the official documents and videos from RaceChip...<br />Thanks a lot, and keep up the good work. individuohttps://www.blogger.com/profile/13986014828143906052noreply@blogger.comtag:blogger.com,1999:blog-6053337542597571017.post-33086516024076472192018-01-02T10:43:14.696+01:002018-01-02T10:43:14.696+01:00The DPF usually has a pressure sensor to signal if...The DPF usually has a pressure sensor to signal if it's clogged, it should show up as a fault. In my case, the sensor got bad and I got faults with and without the unit.<br />The Racechip has a setting for setting the maximum RPM but I don't think it has one for the minimum. Either way, this design cannot take RPM into consideration, only fuel presure, so the only advice I can offer is to lower the setting on your unit (first encoder, by 1 click) and see if the behavior improves.Ligiushttps://www.blogger.com/profile/04631687424641789584noreply@blogger.comtag:blogger.com,1999:blog-6053337542597571017.post-1202554384227472862018-01-02T00:31:09.593+01:002018-01-02T00:31:09.593+01:00I'm hoping you could help me on an issue I am ...I'm hoping you could help me on an issue I am having with my Racechip box.<br />I have had it fitted to my car for about 3 years and now recently the car has started cutting out when at low rpm, (i.e. when approaching a junction slowing down and the engine goes below 1500-2000rpm). I have only noticed the problem after a few hours of driving and only after sitting in heavy traffic which makes me think it could be to do with a DPF regen as you mentioned before. When the car cuts out no engine warning light comes on or error codes and the car restarts as if the car has stalled. Since removing the tuning box the issue has not occurred once. Any ideas or advice would be appreciated.<br />Thanks<br />JonnyAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6053337542597571017.post-90303038814851386512016-09-02T07:35:59.672+02:002016-09-02T07:35:59.672+02:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/09133724760347992840noreply@blogger.com
