Doesn't the Ford ECU register fault codes for overboost and other adjustments. Even though the service department may say nothing about the fault codes they may still be aware the vehicle is modified.

We check for fault codes after the unichip install and I have not a seen an overboost fault code on a customers xr6t.

As stated APS users who have modded injectors can no longer believe the DTE (Distance to empty)computer which to me shows the ecu still see an injector duty cycle but cannot and do not compensate for the larger cc's of the injector. Won't the computer become confused as in the 5psi is clamped output. waste gate controls would be different temperatures etc. etc. Does the Unichip allow mapping and corresponding formulas to allow scaling ratios or is the 5PSi just clamped as the throttle is depressed. Surely this would be recorded as a fault. What happens in an overboost situation how does the unichip save the engine. Does the unchip use the knock sensors on the vehicle.

What I do know is that the Unichip can handle nearly all of the latest BOSCH motronic engine management systems (Porsche, BMW, Mercedes, etc., etc) the question is what other brand of interceptors can? :lol: PeterAPS Link to comment https://www.fordxr6turbo.com/forum/topic/10445-unichip/#findComment-116698 Share on other sites More sharing options...

Mr Blackbird,If you want proof read this thread...How Detectable Are Unichips?, Can they be easily found by dealers?

aps Member 1,505 Member For: 22y 1m 26d Posted 30/04/04 04:23 AM Share Posted 30/04/04 04:23 AM (edited) SR71, regarding that thread you mentioned initially, I read it and all I can say is that the technical information presented is just plain wrong in relation to the Unichip – even more so on an XR6T.Regarding your other questions:1. The DTE function relies on injector duty cycle. Any mod to fuel flow or fuel pressure will cause a variance. Similarly, as the fuel pressure drops with age, DTE will change also.2. Yes, Unichip senses boost pressure and precisely maps EFI parameters for increased boost pressure.3. Unichip does not affect the Ford knock sensor circuit operation. In any case, your questions apply equally to any engine management system. Perhaps you should ask the same of others instead of targeting APS. In addition, it would be more productive for all forum members if you kept your questions specific to the XR6T.PeterAPS Edited 30/04/04 04:30 AM by aps Link to comment https://www.fordxr6turbo.com/forum/topic/10445-unichip/#findComment-116806 Share on other sites More sharing options...
