Got it all for roughly $750

 

Thats not too bad of a price, how do you tune the fuel? Is is an older analog system?

 

It's the self-tuning type. I havent decided if I'm going to wire it with a TPI ecm, or get a commander 950 to tune it. I'll be spending the next week or so in the DIY efi section The manifold is going to take a trip through the sand blaster.

 

Self tuning?

I think this is a perfect application for megasquirt personally.

 

That's an oxymoron, unless you meant "yourself-tuning" type!!

Pretty good deal, though. I'm curious as to what type of computer/harness setup came with it.

 

lol, no it really is SELF TUNING. Basic stuff like idle speed is required to be tuned by the user, but the ECM tunes and retunes the fuel-map and spark as needed based on the sensors i.e. o2 sensor. Sounds good huh? Not really. You cant just put in a basic fuel map and tune from there....you have to throttle through all of the RPMS under load, from idle all the way to WOT, and hold each RPM for at least 10 seconds.....not easy The manual estimates around 8 hours of continuous tuning like this to get it right. Thats 8 hours of continuous, under load tuning. I dont think i have enough money for the gas, nor the money to put it on a dyno for that long to tune it standing still.

 

Oh yeah, a few details about it. Included everything mentioned above, plus it is a complete stand-alone. The ECM comes mounted on the driver fuel-rail for easy access. The whole system is contained completely under the hood, except for the fuel pump of course, even it did come with 3 of them, all 3 high PSI, but each rated at different gph. The system uses IAC, TPS, IAT, Water temp, O2, MAP, all relays.

 

mhaskell..good point. I have been researching megasquirt for quite some time, and they seem to be on top of their stuff. I of course would get a non-assembled one, so i can solder it all together (electrical/photonics engineer major).

 

Self tuning? It self tunes to what? I didn't see mention of a wideband, and cutler is too old to have one anyway i think.

I wonder how WOT is tuned without knowing AFR. I'd trash that system and just pick up a MS for $140

 

....still curious as to what brand/manufacturer this self-tuning ecm ect. this is.........

as for the 8 hours of tuning, spend and hour on the dyno and the other 7 drinking

 

9.0 USING THE ECM

The ecm is very simple and easy to operate. It can learn most functions needed to run an engine on its own, however there are several features and adjustments that need to be explained.

9.1-9.9 Priming, idle system, etc.

10.0 GENERAL TUNING INFORMATION

The ecm tunes by seeking out the peak torque an engine can produce at a given load. After every new point is tuned the ecm uses this new point as well as all the other previously tuned points to build a fuel map optimized for the engine.

The ecm is used on a variety of engine sizes and power ratings. Until the ecm has learned about your engine it may cause the engine to run rich. It may take several minutes to tun these first points correctly. As the ecm gathers more information about the engine and has built a more accurate fuel map, the final points the ecm tunes will take less time than the first points.

The ecm is tuning correctly when the Check Engine light is solidly on and the engine is either increasing in RPM or running at a constant RPM. Because the ecm has to wait for engine performance data to analyze and tune the engine, the lower the RPM the longer the ecm takes to tune. At 900 RPM the ecm can take up to 10 minutes to tune a point. At 3000 RPM, the ecm can tune a point in less than a minute.

When the ecm encounters an un-tuned point it will immediately start to tune. If during the first 8 hours of operation the vehicle stays at a load point for more than one minute the ecm will re-tune this point. After 8 hours the ecm will re-tune load points whenever the engine stays at a given load point for more than five minutes.

For the ecm to build an accurate fuel map it is very important that the ecm be allowed to tune every point it can. To optimize the tuning process, the engine needs to be kept under constant load until the ecm has finished tuning.


Thats where I'm stopping...about 80 pages of installing, tracing error codes, and "tuning." Much easier to throw on a MS and do it yourself. See what I mean now?
