HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

been a while since i had an update. the car has been put away for a couple months now, had a great summer of driving it and im now in winter mod mode. i did end up getting my swaybars installed over the summer, they made a massive difference in the car. i decided against my better judgement to take the car to the dragstrip in september, and promised myself id just drive it off the line. made 2 easy passes doing just that, ran 13.8s at 118 mph with terrible 2.7 60' times, thanks to the turbo 3.38 final drive. i decided on my last pass that id try to leave with a little rpm and just kinda slide the clutch out and feed it throttle. great idea in theory, left around 3000 rpm and as soon as the engine saw some load it came alive as it hit 15 psi nearly instantly (my data log graph showed the boost as a near vertical line). car squatted real hard, it got about 60' and broke the passenger side axle cage. the failure points to the axle breaking from too much angle, ill be fixing that with a set of rear bump stops, and will likely be building a set of axles for it over winter. im sure had it not broken it would have been the low 12 i thought it would run, but thats just bench racing at its best.

so right now ive got the trans out and am about 3/4 of the way through a gear swap. i picked up a 3.875 final drive from an AOS/AOT s2 transaxle. im also swapping 5th gear to the tall n/a gearset. the n/a transaxle was always better suited gearing wise to my engine combo, when i put the turbo transaxle in it kinda felt like i neutered the car, despite having 100 more hp.

another big change im making is im changing my engine management. ive had nothing but issues with the microtech system (admitted some self inflicted), and after it took 6 months to come back from service and then the idle circuit was dead, im done with it. in its place i decided to build a megasquirt ms3x system. ive done several megasquirt projects myself in the past, albeit quite a number of years ago, but they have always worked out well. i think the biggest draw at this point for me is if something goes wrong i can troubleshoot and repair it myself.

the ms3x will give me full sequential fuel and ignition, gm 4 wire idle control, 4 bar map sensor, real time barometric correction, and a bunch of other stuff. some of the optional things ive decided to do is adding fuel pressure and oil pressure sensors, an oil temp sensor, and a gearbox temp sensor. ill be able to control cooling fans on my trans cooler with it, i can control the accusump directly from the ecm. a vss input will allow me to run simple traction control as well as boost control by gear. if i wanted to (and i may in the future) i can directly control the water/methanol system. after running such an antiquated system with such basic control im really looking forward to getting this built and in the car.

This is a phenomenal thread on an incredible swap. You have some serious skills; you should consider writing a book, or a step-by-step instruction manual, to fill in the blanks you understandably weren't able to cover in this thread. If I ever do a swap with my 968, it would be something like this, a Mitsubishi 4B11T, or any of a number of stout modern 4-cylinder turbos. Just not a V8 guy, although I respect V8 swaps as well.

A couple of questions: Any idea of the weight of the Ecoboost engine, including the turbo and all associated hardware, vs. the stock 944 engine? And did you consider a dry sump, vs. fabricating your own oil pan?

Thanks again for sharing your amazing journey.

i did consider going dry sump, a couple things turned me off of that. i dont like a belt drive oil pump on a street car, and it just wasnt in the budget. it would have alleviated some problems, but caused even more, and i still would have had to build my own pan (the available ecotec drysump pans still wont fit the 944 chassis).

the 944 n/a engine is between 370 and 400lbs (according to the internet), the 2.3l ecoboost is around 340lbs complete. my ecotec is around the same weight.

thanks for the kind words. ive been kind of lacking on my updates in the last while, i think im just not finding my swap quite as cool as i did when i was building it. i work for a hot rod shop, i get to build all sorts of cool cars for people, my little 944 is what i can afford for myself, and i do really enjoy it. right now im working on a 65 impala thats powered by a maserati 4.2l dry sump engine. we developed a way to mate the engine to a tremec t56 magnum, its got a single borg warner efr turbo on it. this past year we took our little mazda r100 to the sema show and ended up in the battle of the builders top 4, winning the sport compact class. if you wanna check them out, go in instagram and look up hotrodsrestos.

i spent new years working on the ecm, im pretty well done now. 

[You must be registered and logged in to see this image.]

the main board near complete. 
[You must be registered and logged in to see this image.]

an additional temp sensor input circuit

[You must be registered and logged in to see this image.]

all the jumpers on the bottom of the board, and the upgraded 4 bar map sensor (max of 44 psi). it also has a barometric pressure sensor for real time altitude correction

[You must be registered and logged in to see this image.]

the white board is the processor daughterboard, the little green board on top of it (under the ribbon cable) is the knock module, this allows inputs for 2 broadband knock sensors. the green board to the right is the ms3x expansion board, this where all the extra inputs and outputs are. 

[You must be registered and logged in to see this image.]

so aside from the usual inputs (crank sensor, coolant, tps, manifold temp, and wideband o2) ive got it set up to run a cam sensor (that will allow full sequential fuel and spark), flex fuel sensor, vehicle speed sensor (allows it to use engine states for more accurate fueling, along with boost by gear and simple traction control), oil pressure sensor, fuel pressure sensor, engine oil temp sensor, gearbox temp sensor and a clutch switch input. after some fiddling around ive been able to get it to control my trans cooler fans, my accusump oil accumulator, and a shift light (that can be programmed for different rpm in each gear). ive still got a 3 digital inputs and at least 10 outputs i can use if i can dream up more things to monitor and control. and if thats not enough i can add in 32 channels through can bus (considering the 4 channel egt module). 

the cam sensor is something i have yet to sort out, seeing my engine is an early (02-06) l61, with no provisions for a cam sensor. i have a threaded body cam sensor on order, im thinking of drilling the front of the head and using the front of the cam gear as a trigger wheel. ill have to add something to act as a tooth, im hoping i can thread one of the holes and using a bolt, but im still unsure of the best route to go.
