I am now the proud owner of an AEM intinity-8 and waiting for my EngineLab EL Console access.

I setup a separate place on my other forum for it:
http://gemellocattivo.com/forum/viewforum.php?f=18

Marcus is very hard at work on o5e hardware so I'm still planning to install/test that but the EL system will let me develop/test logic and control strategy stuff quickly and easily before transferring it into the 05e code.

I'm starting to have some fun with the EngineLab thing......documentation is a bit weak and with no examples its a challenge to sort out but I'm getting there I think.

I'm doing a few things differently from how I originally setup o5e so if they seem to work out I'll transfer them to o5e too.

I'm finally back to the ferrari.

The mufflers are not connected and I'm starting to add the O2 bungs...all 4 of 14 are done.

I've been using my lunch time to write the "model" that goes into the engine lab ECU and I think the fuel and spark are about done and seem to be working right. I just finished the accel/decel correction stuff which was the last piece for fuel and it seems to do what it's supposed to do.

A couple screen shots of it running in simulation mode
Red is MAP, I made step changes to simulate mashing the throttle
Blue is the normal Fuel for the current air flow
Purple is the actual fuel delivered by the injector with the accel/decel correction applied.

The system is based on fuel "store" in the intake
Green is what should be in the intake
Gold is what's actually in the intake at any given time


....now I just need to actually finish the engine :lol:

I got the rear bank sensors finished and I'm pretty happy they came out neat....now I just hope they don't fry so close to the port.

On to the front bank.

yes.... and now that all 14 bungs are finished I've decided that if I just put 4 NB sensors in the 3-1 collectors + crank position I should get just as much data and less wires and no chance of frying the sensors. Time it install 4 more bungs and just use the 12 pipe bungs for trouble shooting of maybe TCs

So here's the layout for the NBO2 stuff. I think it came out pretty good....hopefully it work the way I think it will.

It's got the following inputs:
Widow - how many degrees you want to look at

open angle - when you want to open each window.

latency - degrees it takes from the open angle until you see the signal at the sensor at different rpm

Voltage to lambda conversion data....I like to keep things in lambda even if I'm lying to myself a bit with NB readings.

I was surprised how much work this was. The run the engine code is currently 235 lines, this added 190 more lines. Engine lab is set up to make normal engine stuff easy so a lot of thinking about what I wanted but not a lot of lines of code but this was a lot of thinking about what I wanted and how to make the code do it.

I still want to do something to calibrate to the bank WBO2 sensors so I have decent high speed cylinder O2 away from stoich....but this is good for now.

Well that's interesting, I wouldn't have thought the sensors were fast enough. Do you have any idea what the frequency response of the those sensors is?

A NBO2 sensor has a response time under 2msec from everything I've read vs an average WBO2 that is more like 150msec. The innovate LC-2 digital WB controller claims under 25msec with I think 10msec typical so at lower rpm they would probably work too and may be my fall back is the NB don't work the way I thing they will.

While I was grabbing the oil filters so I could fit the remote filter mount I picked up a new battery to help with measuring up what I need for a battery cable. The old alternator lead bolted to the old batter lead is just about perfect.....which of course led to "I wonder if it cranks over?

Oh yes it does :)

I forget all the exact numbers but its got a 10" (?) F360 flywheel ring gear on a custom flywheel replacing the 12.5"? 400i flywheel. Then an aftermarket gear reduction starter from a chevy adapted on. So just that that all worked right was good, the no parts crashing in the engine was gravy :)

The oil filter housing pissed me off when I realized the fitting bosses are too close together to actually put fittings on so I had to one of them....but it's done and looks neat now.

It's also got an oil tank now....which of course I couldn't bring myself to leave alone and just install.

I cut notches in the back to clear the frame so it tucked in neater, moved all the fitting so the hoses will fit neater and added an additional 3.5 quarts so it should be about 7 quarts to the fill line and 10 quarts total in the tank plus 2 in the filters and another 1-2 in the engine and lines. I didn't install an oil cooler....I'll see how oil temps do.

I was messing with the ECU a bit. I used my o5e to supply crank and cam signals to the AEM/enginelab unit and confirmed that while it's called an infinity-8 and advertised with 8 spark/8 fuel it actually has 10 spark and 12 fuel.

I was told if I removed 1 0R resistor and added 2 others I could get 12 spark....not so. I did find an 11th spark signal at one of the resistors I added but the signal is inverted and doesn't get to the header. At the other resistor I found an uninteresting 5V. So question back out about what else may need to change.

The worst that happens is I run waste spark but I'd like to have 12 spark outputs

A very boring morning in the shop. I cleaned up a bit of the huge mess the oil tank project left then on to the excitement of measuring oil line and ordering fitting! I think that's all sorted now.

I also have for venting the crank case which I'd forgotten about. I'm going to add 1/2" hose barbs to 2 or the little teardrop caps on the front of the engine, they will T to a 3/4" hose and go to the top fitting on the line tank, then the tank will get a 1/2" vent......that I may run to the air box, not sure about that yet.

I checked the clearances for the oil lines with the wheel on to refresh my memory. The pic makes it look tighter than is, there's nearly a full 3/4"...plenty.....I hope.

Then I decided I didn't really like the angle the water pump feed was sitting at and since I needed to add a fitting for a by-pass line anyway I cut it off and performed a little tig welding magic. I think I have a good plan for all the coolant lines now.....we'll see how it goes tomorrow when I try to make the plan reality.

So I got a brand new and nice 1996 (I think) mustang T-stat housing......which I decided to cut to bits :lol:

I think the t'stat and lines are now good to go.

MoTeC products are now officially on my "do not buy" list...the company is infested with lying assholes as far as I can tell.

since I've decide to go with the enginelab ECU until there is a suitable o5e option I have my M150 on ebay and buyers are all trained to call before buying because any unit reported stolen will be killed the next time it connects to the tuning software so best to call and check before buying. I have lost a couple sales that I know of because I got angry notes that the listing should be removed and the ECU is unusable. The first time I thought the guy was nuts, but the second guy started by saying he spoke to motec east and......

Apparently when potential buyers call the guy at motec east has been leading them to believe the unit is "blacklisted" because I modified it (then unmodified it which I was honest about in the listing) so it and can never be used again, much like a stolen unit. There's no such thing as a "black list" of course and they deny saying that, and agree that all anyone needs to do to use it is purchase a firmware license just like my ad says and they have no way of knowing anything at all is wrong with the unit....but I've heard a very similar story from 2 lost buyers now and I strongly suspect there are more I don't know about. They also apparently went off on the dealer I bought it from for letting me modify it as if he or they had any say in what I do with my property.

I explained my displeasure with their behavior yesterday and hopefully made it clear that the next time they speak to someone about this ECU they best choose their words carefully and stick to the facts so their are no further "misunderstandings" about the condition and status of this ECU.

This thing has done nothing but piss me off since I got it with the way everything is crippled is some way to force upgrades or additional purchases. Fucking MoTeC

Nothing real exciting but alternator is in, belt on and a lot of hoses being run. I ordered about $700 or wire and connectors last night so in a week or so wiring can begin.

A little bit exiting is I put oil in the engine (the system holds 11-12 quarts it looks like) and get oil pressure during cranking, good return to the tank and the oil seems to be leaking anywhere which is a minor miracle considering all the welding :)

I've been working with the guys at enginelab and they have been making some nice refinements the latest which will come in really handy as I get ready to wire is a pin-out that tells you exactly what you've assigned to which pin. If you want to change something you just double click it and the model items opens and lets you edit or reassign it as you please which makes it even nicer than the motec version which is info only.

I'm very close to having my 12 spark outputs. I had to add 2 more jumpers to the board (so 1 off, 4 on total) and that got signals to the pins but not the right signals so they are making a FW update to correct that for me.

I can't wait to get this thing hooked up!

I think all the wiring stuff is here now, at least everything thing I ordered is....other than the actual ECU plug....not sure where that is.

All kinds of colors of aircraft grade wire! and lots of connectors, I got the the Deutsch DTM type with the E007 back which allows heat shrink to grab the shell. I also go a couple spools of 2 and 3 conductor shielded wire that I'll use for all the sensors so I can be pretty certain to get clean signals to the ECU.

Then I bought a couple Hella 4 relay boxes and their 8 fuse box.....pretty nice parts. I also bought a bunch of standard relays casue they're pretty cheap and 1 more pricey solid state relay for the fuel pump because I want to PWM the signal to control the pump speed and therefore the fuel pressure.

Now I just need time to actually do the wiring.....throttle bodies first though.

The fuel lines were not placing nice, but I think it's sorted now. I added the fuel pressure and furle temp sensors to the regulator, moved the fuel pump a little to get the line past the bellhousing, fuel filter up over the trans, and modified the fuel rail to snake out around the linkage. IT's seems good.

The wiring has finally begun! First up was a fuel sub-harness because there is flat no way to get near the injectors once the intakes are installed. I had a mis-start last week when I just forgot what I was doing with wire colors so I had a do-over to replace the black with a red version. Its done now other than holding on heat shrink that fits over the connector properly.....although it would be easier to see what I have where if I leave 1/2" of exposed with like I did up near the injectors....hmmmmmm

This afternoon I Got the TBs installed. It took some thinking time over the past few days to figure out how to get them in place and it's definitely a "WTF was the engineer thinking!" setup. Ooops!

......but it fits (once I ground enough and kind of rolled it all into place in the right order) and looks neat so......hopefully nothing leaks!

You know.....I hadn't really thought about that. I did go to some trouble to put a ferrari on the valve covers and make them look like what ferrari was doing on their V engines than the flat engines though.
