Looking at my Heywood shows there is a very significant change in the output of the sensor with the change in the sensor temperature. The higher the temperature, the lower the output voltage. This is over a range of at least 200mv. The stoic switch over can take place anywhere from 650mv to 875mv depending on temperature. One consequence of this is the cooler the sensor, the leaner the mixture for any temperature over stoic crossover. Bob Hale has pointed out that the heater resistance increases rapidly with temperature. Questions Does the O2 output vary by the heat of the gas or by the heat of the sensor? By gas - can the heater be used to measure the temperature of the gas by switching it over to measuring resistance when the sensor is warmed up? By sensor - would a current regulator circuit be useful to keep the sensor at a constant known temperature after warmup. Inquiring minds want to know.

Any thoughts? ------------------------------ Date: Tue, 30 Mar 1999 12:05:53 -0800 From: rr Subject: '747 ignition only system Did some additional testing. This is definately a valid setup. Here's a list of components that are in place: Small cap HEI 7-terminal distributor Coil, manifold mounted Coolant temp sensor VSS, optical unit Knock sensor and filter I didn't use the TPS sensor, for a more permanent system it might help to install it on the carb. I'm going to a TBI system, so I don't want to put the time into mounting it to the carb. For the main timing table, I've tried the stock table, tables that mimic a centrifigual advance only distrib, and one that Bruce used in one of his vehicles. They all worked, with differences in idle speed, knock counts and responsive-ness between them. I also made some minor changes to the PE values and cold/warm spark bias's. In the eprom, I killed the error codes for the O2 sensor, EGR and the TPS, numbers: 13, 44, 45 & 32 & 21, 22. The error code the the fuel pump voltage is off: #54, this is stock for this eprom. I have disconnected the fp relay, with no error codes. So, it's not needed. Per the archives, I disabled the EGR entirely (This is a non-egr vehicle): 1b8 = fd, 1b9 = ff, 1bf = 0 I am getting no error codes, no limp mode, just a solid ignition setup. It does run better than just the old normal ignition, as there is better control over the timing. Timing is added during warmup to help prevent stalling, the knock sensor and filter are in place to prevent ping and hot starts work as the timing is backed down so the engine will crank. Without the o2 sensor, the ecm never goes into closed loop, so the int and blm stay at 128. The iac counts change, but so what, there's no iac! Backup mode (limp) does work, I put it into that mode with the scanner, and the car was driveable. I think I'll throw the bin into 'incoming', this way whoever is interested in it can take a look at it. Look for a future post on when it makes it in.

Does that name ring a bell? He was a big name in bike racing in the '60s and '70s. Used to write a column called "Ask the Assassin" in one of the ragazines. "Atcheson, Topeka, & Santa Fe" was the name of his bored, stroked, triple engine Honda drag bike. Hilborn injection running nitromethane, with a little nitrous oxide plumbed in for grins. Got into trouble on a run, the bike went into a speed wobble, flipped, and over half a ton of machinery got on top and rode him down the track a ways at over 150mph. Collins salvaged the engine pod, put a sheet of glass on the top, and uses it as a coffee table. After the orthopedic surgeons got finished wiring him back together he drew up plans for a new bike, a supercharged V8 made by siamesing two Kawasaki fours together. His shop built the bike while he was in the hospital. When it was finished they brought him to the strip in a wheelchair, with casts modified so he could ride the bike.

Looks like he is still kicking butt, but now his specialty is EFI. Does anyone know about his products? Specifically I am looking at the high impedance injectors. I am hoping to use a 749 ecm to control a big hp motor. He is a thumbnail sketch. I am planning, and actually building, a 1946 Buick Street Rod. It will be powered by a 540 ci. Caddy, port fuel injected by via the adaptation of a Ford 460 MPI manifold. Now this is where I get the looks. It is going to be turbocharged. The turbo is more for novelty, kinda keeping with a Buick theme. The motor made 400 hp and 550 ft/lbs in stock form as a 500 ci. I am guessing with all of the mods the hp will be significantly more so let's say 800 hp at 15-18 lbs of boost isn't unreasonable. These RC injectors may be the ticket for allowing the 749 to control the beast. Thanks, Paul Tholey PS.

While on our diesel, just kinda interesting. None intercooled, 436 CID, 60 PSI boost, 90%VE. yeilds almost 500dF of intake charge temperature. (also 2,000HP, and 1,700 ft/ls Tor.) prolly off from that but just a hint of what it's doing. BTW, dumping as much water as we do, the number jump up.. On a 440 (-+) v-8 running 10 PSI boost IAT @ VE 110% always around 300dF Would take well over 95% Efficency Intercooler to get "reasonable". 50-80% drops IAT like 150dF. Will take a ton of intercooler to get under 150dF IAT Doc ------------------------------ Date: Tue, 30 Mar 1999 17:58:17 -0500 From: "Bruce Plecan" Subject: Re: Chip for Northstar Is this from Melissa?

I am not sure this will work if the system looks for other things such as break effectiveness or missing output actuators. The best answer i think is to install the axel speed sensors. I doubt that the Caddy ECM is well hacked or documented this is probably why a chip is hard to find. If you can afford a Caddy there are several alternatives for the money. The best answer may be to wait for the popularity or these engines to catch on. There may be some applicable information available for the Olds Arrora of Vett ZR1, Not sure all the differences and similaritys.

(True or False?). The rear O2 sensor would run cooler then the front. So, the rear O2 in order to measure the effectiveness of the cat would need to operate at least at the same temp as the front. So it would need a "better" heater. Since it might not track the front too well, then it's "range" would need to be greater. Only have any documents to compare the above to, or does it make sense to someone other than me?.
