85lebaront2 Posted April 6, 2018 Share Posted April 6, 2018 I don't think the 10:1 - 20:1 issue will be an issue. If you get lower than 10:1 it'll probably show 10:1, and that is too rich anyway as you don't want anything richer than about 12:1 for full throttle runs. But, Bill may disagree and I'll defer to him on that. The AEM (30-4110) UEGO Air/Fuel Ratio Gauge is basically the one I have, although mines called Fail Safe so has another function that we won't use as it has to do with boost. Mine has worked well and I plan to use it to tune both Big Blue and Dad's EEC-V systems. However, my understanding of tuning those systems is that you get it in range for the open-loop time, but it then fine tunes that when it goes closed-loop. Ok, several items, first, I bought my wideband Innovate unit used, after about 2 years the Bosch sensor failed and was easily replaced with one ordered from Rock Auto. It is not the bells and whistles fancy meter, just a moderate sized box with a digital display and data logging capability. It also has a port for connecting to a computer for either live data or to download logs. For Gary's use it has to be able to integrate with the tuning software or it is essentially useless. Second, max power on gasoline is at 12.5:1 AFR, the Core Tuning software can be set to go there at WOT in open loop, closed loop can be set over a range the regular O2 sensors run in. for gasoline that is 14.6:1, with the corn blend, it is a little different. I will get a picture of mine later, my sensor is in the H between the pipes where the factory single O2 sensor was located. Link to comment Share on other sites More sharing options...
Bruno2 Posted April 7, 2018 Author Share Posted April 7, 2018 This is an interesting read and worth the time IMO: https://10carbest.com/best-wideband-gauges On a set up like Jr or even the Bronco is range of 10:1 - 20:1 going to be adequate or do I need to spend the money and buy the unit that starts at 8:1 ? I bought this one: https://www.ebay.com/itm/AEM-30-0300-X-Series-Wideband-Gauge-AFR-O2-UEGO-Air-Fuel-Ratio-2-1-16-NEW-MODEL/172533722726?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 I just couldnt make myself go with Innovate after what has been said about their customer service. Nobody should have 3 pages of 1 star reviews on a platform as big as Amazon. The "care" factor just isnt present. Anybody that cares about their business, customers and product line should have gotten in front of that a long time ago. Some other forums and automotive publications gave their products good reviews. However , AEM has good ones too. I guess only time will tell if I made a sound decision or not, but this model is noted to have the quickest register time. Link to comment Share on other sites More sharing options...

Having the concern about customer service running around in your mind isn't worth it, and the AEM gets good reviews. Mine works fine. Link to comment Share on other sites More sharing options...

Gary Lewis Posted April 8, 2018 Share Posted April 8, 2018 Ok, here is mine, the couple of times I have contacted Innovate I had no problems at all. As you can see from the first AFR reading, 460s run lean during warm up, I could probably tweak it but it doesn't seem to be an issue. If the power to the EEC keep alive is interrupted then it will go way lean the first start. I wouldn't have thought that 15:1 was very lean during warm up. I'm assuming that "warm up" means open loop, and that during that time it is just running off the tables - right? So, you could tweak the tables and dial it in if needed. How much does that AFR vary due to temp? I assume that the colder it gets the leaner it is. Or, do the tables include temp? What about atmospheric pressure? Just thinking ahead.....

Gary, it had already started to settle in, but at the first readings cold it will be 16:1 and sometimes even leaner. The factory "tune" on the SD engines has them so lean on cold starts they are prone to stalling. On the tables, yes, it monitors ACT, ECT, MAF signal for open loop running and if I take a quick glance at it while under load it will be dropping toward 12.5:1, moderate throttle, usually drop to 13:1. I can send you one or more datalogs I did for Adam, they export in Excel form and the columns have the parameters on them and I believe the Innovate output is one of them. Not everything is logged, only what is needed for the particular "test run". Link to comment Share on other sites More sharing options...

I plan to buy the Core Tuning package in a few weeks so want to start thinking about that again. But 16:1 is a bit lean, although if the engine doesn't mind I guess it isn't a problem. I'd think that is on the verge of stalling with a cold engine, but if it works.... By the way, USPS didn't deliver the plenum yesterday. But they did deliver the 1982 Facts Organizer Jonathan sent, so they did come by. Link to comment Share on other sites More sharing options...

Gary Lewis Posted April 9, 2018 Share Posted April 9, 2018 Data log was sent, have fun! At least I have it exporting in Excel. Bill - Got the data log, thanks. I have some questions but will ask them under separate cover. As for the plenum, guess I'll ship yours in a different box. As for the plenum itself, you said it was stripped out, but apparently the USPS ran bolts in and then twisted them off. Seriously though, now I understand why you wanted another one. When you said a bolt hole was stripped out I thought it would be cheaper to helicoil it than ship it two times. But, getting those things out of aluminium wouldn't be easy. I'm thinking I'll hacksaw the bulk of that part of the casting off, do a bit of milling, and then round the corners w/a flap wheel. And, while I see what you mean about running a tap deeper and blocking the whole thing off with a plug in the back, I think I want to tap and plug the side hole as well just for to make it look better.
