merckx Posted January 1, 2006 Share Posted January 1, 2006 Following on from the BPU thread. So for BPU , which would give priority and why. EGT gauge or Wide band O2 gauge I've done a search on here and elsewhere , they're so many conflicting views. I know they're not totally necessary but it would be nice to keep an eye on things engine wise just incase. Would an EGT gauge indicate a lean mixture by an increase in temp and the same if the air charge gets too high, whereas a wideband would only indicate the obvious A/F ratio.

SupraHuman Posted January 1, 2006 Share Posted January 1, 2006 I just installed the Innovate Motorsport WBO2 sensor and gauge(yesterday:)) works a treat and is fully programmable. Quote Link to comment Share on other sites More sharing options...
JohnA Posted January 1, 2006 Share Posted January 1, 2006 EGTs should always be interpreted in the context of AFR. If you're running very lean the EGTs will be getting lower but for the wrong reasons. If you have to choose one of the two, Wideband wins every time.

Tricky-Ricky Posted January 1, 2006 Share Posted January 1, 2006 Inovate wideband, EGT is only really useful if it fitted in the right place, before the turbos, which is risky as the thermocouples have been know to break! so it can be by by tubby! and although they can give an indication of fueling, they are just as susceptible to timing changes.

baldy Posted January 1, 2006 Share Posted January 1, 2006 . If you're running very lean the EGTs will be getting lower but for the wrong reasons. i stand to be corrected but i thoght lean ment hotter= egt's higher yes no ??? Quote Link to comment Share on other sites More sharing options...
JohnA Posted January 1, 2006 Share Posted January 1, 2006 not necessarily. If you're running leaner than stoich then there may not be enough fuel to create the high EGTs. After all, pure air can create no heat, no? Quote Link to comment Share on other sites More sharing options...
Lucifer Posted January 1, 2006 Share Posted January 1, 2006 1 AFR 2. EGT Good to have both Quote Link to comment Share on other sites More sharing options...
merckx Posted January 1, 2006 Author Share Posted January 1, 2006 Thanks everyone I think the AEM also does A/F ratio and Lambda. There doesn't appear to be much difference between the Innovate and AEM units apart from the Innovate having a record button. Innovate better than AEM?

Wez Posted January 1, 2006 Share Posted January 1, 2006 AFR first then EGT but both are good AEM are fine, i have an AEM WB non gauge version wired into my AEM ECU. Quote Link to comment Share on other sites More sharing options...

The best place for the Innovate sensor is just before your first cat if you got one,or 2-3' from the end of the tail pipe. Quote Link to comment Share on other sites More sharing options...
chilli Posted January 1, 2006 Share Posted January 1, 2006 good question, I've been thinking of this as my next mod. With a good AFR gauge, is it possible to dispense with the EGT gauge altogether? Or can it indicate something wrong elsewhere not attributable to wrong AFRs? Quote Link to comment Share on other sites More sharing options...
JohnA Posted January 1, 2006 Share Posted January 1, 2006 Ideally you want to have both, especially if you intend to push the envelope Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 1, 2006 Share Posted January 1, 2006 The best place for the Innovate sensor is just before your first cat if you got one,or 2-3' from the end of the tail pipe. I was talking about the EGT sensor not wideband! if you place a wideband sensor to close to the turbo, it will cause overheat errors, the best place if you still have a cat is just before it, but you may still suffer from overheat errors (odd readings) you can fit a heat shield, that may help, i needed one and my sensor is a good 2.5 feet from the turbo, if you have no cats then anywhere thats not to close to turbo or tailpipe, and i would recommend the innovate on the data log feature and the logworks software, you can log six different inputs, very useful:yes: an EGT gauge can wait, especially if your not going to place the thermocouple before the turbos, otherwise it just guesswork.

Peter10654 Posted January 2, 2006 Share Posted January 2, 2006 If you use a AEM EMS i would think it is easier to plug in the AEM Wideband. There is a Button in the EMS Software you can choose AEM Wideband or FJO Wideband. You don't need any calibration or adjustment in the EMS. But if you don't have a AEM EMS i would prefer the Innovate XD-1. Cheers Peter Quote Link to comment Share on other sites More sharing options...
Wez Posted January 2, 2006 Share Posted January 2, 2006 The AEM gauges work fine without any EMS connection, they just have 0-5v and 0-1v outputs for EMS connection if you want it. Quote Link to comment Share on other sites More sharing options...
