Did you ever post up your 10psi dyno? I would love to see that run overlaid with your 20psi run.

All I have is a video clip of it dynoed, and at the end it shows the graph.

I would love to see a 20psi run too, but I'm dealing with boost spiking right now, so im playing with the duty cycle and such until I get it right, then I'll dyno it

Awesome stuff. Congrats on getting your car to a place where I expect very few other 325 owners are at.

This certainly gives me hope for a year or so down the line..I just got the Technique Tuning kit for my 330. But in the end I want to run E85 and a bit more power on the stock block, so I will eventually do ProEFI. Nice to hear that it can be made to work.

Thanks Matt. I can see why there are rare to find boosted 323s 325s etc due to the small amount of power they have from the factory.

At one point I wanted to do a TT kit from them, but they didn't have a kit (only for 330s at the time) and wanted ~8k for it when I realized your mainly paying for a tune.

After doing extensive research, and my natural way of tweaking things, the technique tuning kit wouldn't be a fit for me anyways. for a couple reasons but I'll just name a few:

- the safety features are only as good as stock (knock control to cut timing) in that setup there is NO fuel pressure safety in the event of pressure drop or loss of a pump completely.

- in the TT kit you cannot tweak the tune if you change your setup, you have to get it retuned by Nick G.

- NO flex support where one can run any mixture of E85 with the ECU making on the fly adjustments to boost, spark, and fueling based on Ethanol content

- tweakable traction control

-Multiple Fault Management strategies to save the engine and alert the driver incase of sensor failure or tuning errors.

There was a 330 at Pro EFI's shop that apparently had all the CAN working with the EMS so there is good hope. Mine is 90% with the CAN, but I'll have to do more R & D to get it to 100%


the list can go on. BTW Pro EFI does not indorse me to talk about their product..

Ive been lurking for a while to figure out how, Ive wanted to turbo my 325i for a while. But who tuned it or how did you? How did you build your own kit?

I had a guy in Long beach hold my hand on tuning it. Due to the software difference and inexperience with tuning in general

As-far-as how I built my own kit. I just looked around at m52/e36 builds and got ideas. other than that Ive changed my setup several times A.K.A trial N error. and the ability to be ballsy and just fabricate things on the spot.

The kit was ~6500, and about 2800 for boost controller, pre and post dyno and installation. I don't think that's bad for what's included. Yes, you are paying for a tune. You're paying for R&D as well. It's not a high volume product.

There are things that can be changed without requiring a re-tune. I can up the boost of the kit, or add in ZHP cams without having to have a re-tune.

The DME has a lot of fault management strategies built-in. You do have a good point about not cutting boost if going lean, etc, but in terms of daily drivability, the stock DME is hard to beat. This is especially true on the ZHP cars and cars similar to mine, which has the non-M SMG transmission. We have the MS45 DME, which has a wideband O2 sensor, so it can correct for variances even at full throttle...

The ProEFI is a good unit. If I didn't think so I wouldn't even consider it. It has the potential to deliver a very good calibration, and does have plenty of safety features.

That being said, if I could adapt the MS45 to do flex-fuel and be done with it, I'd probably do it. But since I can't (at least not without *significant* work), the ProEFI does that and more.

Anyway, not trying to de-rail your thread. I am really happy that you're enjoying your car, as that's the ultimate goal. I am interested in your 20 psi results.

Agreed here is a log of my 20PSI run. I know "potential hp" can be off, but when it dynoed @10psi, the log was not off by much! turbo is apparently pushing 52lbs a min of air

Thanks for posting that.

The question I have is rather complex: What is actual, derived, and estimated in the list of parameters shown?

so basically the EMS takes the values of the density of the air (IAT) the manifold pressure, the volumetric efficiency, injector duty cycle(flow tested) etc and then calculates what the MAF would read (not attached) the HP potential (at crank) and even MPG (from injector pulse with)

Attached is one of my logs (notice the TPS is not fully open(85) so the power is not 100% since I have boost spike. the arrow is pointed to the line where I selected (shows the data at that given point on the right)
