whats a good engine management?

[ttlkaos]

lets see, i am about dew for some bigger and more reliable upgrades and i don't know which one to go with. i was looking at the mpi tuner, the unichip, and even the dsm chip. which one would be the best to go with for driveability and tuning??

 

[KzA]

MPI....the others just cant touch it..theres such a huge knowledge base for the product on this forum that it just cant be beat..Make sure to buy the product straight from MPNick. His customer service is top notch, and has gone above and beyond for me on countless occasions. Some of the biggest powermakers on this forum run that piece of equipment, so rest assure it will do everything you need it to

 

[daedalus]

what are your plans matt? I've had all but the unichip... but had to change and buy new s*** as my plans for the car developed more...

How far do you want to go?

My unichip runs great, I have 3" Turbo-back exhaust, large FMIC, 9-10psi. For out of the box it seems really good, but of course could be tuned even better I am sure.

DSMConvert AFC is a great bang for the buck and it seems the knowledge base and maps are growing on here. There is even a 440 injector map now, but not many are running it. Once I hear of more people running it with sucess, I would be more comfortable. The other maps posted have been running for a while and seem to be a sucess. Remember, this cannot control timing. This is its largest setback.

MPI is the best from what I have read. If you plan to get bigger power down the road (larger / aux injectors), this one can do it. The knowledge base is the largest, and maps are available for multiple setups I believe.

Unichip was great for me because it was PnP, controlled boost and timing (didnt control boost well but dont know if that was just because of my setup). I knew I was not going to build the engine, and that stock fuel system was sufficient.

No matter what you get, get a WB O2. Esp if you plan to just download maps and run them. You want to make sure they are loaded correctly, and make sure with your mods you are running decent A/F's.

Good luck.

Ok sorry... to sum up, I vote for MPI all the way.

dsms afc if you plan on keeping the motor internals stock. MPI or microtech if you are going for a built motor. I dont see the extra cash for a unichip over a afc worth it especially since you cant even tune it without going to a unichip dealer(and then its still proboblems alot of the time i hear)

I hate those damn boots! (far right pic in sig)

MPI or microtech if you can afford them and are planning some really, really big things. i don't know if DSMConvert still has a Fuel and Timing Controller in the works still. but i have his AFC, and i can tell you that once i set the thing back to stock map, my car was notably worse...the super map that came preloaded works great

I can't say very many positive things about the analog control of the MPI, but the way I use it with the FM clamp and extra injectors is awesome. The driveability of the car out of boost and at the boost/vac transition is perfectly smooth (unlike the way my particular MPI unit controlled the stock injectors). AFR is changed by adding fuel with the aux injectors, and spark timing can still be controlled using TPS and RPM. Not only is it better in my opinion for driveability, but the ease of tuning is also greatly simplified.

I personally at this point would reccomend the Microtech unit or AEM unit if you have the dough.

Well I have the DSM AFC and I'd say it's pretty good for fuel. Once you start pushing some power though, you'll need to upgrade the injectors. In my mind, although I have no experience with it, it seems an extra injector setup(ala MPI) is really the way to go.

Does anyone have opinions on at what point I should worry about tuning my spark? I have been thinking about using the JS safeguard in conjunction with the AFC. Is the J&S Safeguard a complete spark timing solution, or would I want something like an MPI on top of that for proper tuning? I still don't fully undersatnd what the capabilities of the J&S are.

 

[jeffmsp]

a afc and j&s is a really good combo.

 

[daedalus]

Look at it this way matt... i'll give you a ride and you'll end up getting a microtech. So just know that if i give ya one, it will end up costing you about a grand!

...In my mind, although I have no experience with it, it seems an extra injector setup(ala MPI) is really the way to go.

It is a good easy solution, and from what I can tell from reading my plugs over the last year, the extra injectors in the charge pipe are mixing the fuel very well. I think that a well tuned bigger injector setup is a little cleaner though, and if it can be tuned right, then it is the better way to go if you are going all out.

Does anyone have opinions on at what point I should worry about tuning my spark?

On my flashed msp, with the 28RS, I start pulling timing for anything above 10psi. 9 and below has worked well on the stock timing for me, as long as the AFR is not much above 12.0:1.

I have been thinking about using the JS safeguard in conjunction with the AFC. Is the J&S Safeguard a complete spark timing solution, or would I want something like an MPI on top of that for proper tuning? I still don't fully undersatnd what the capabilities of the J&S are.

Seems to me that the J&S + AFC would be a pretty good setup. J&S + MPI would be better though because you would have more control and the option of adding the aux injectors.

get an MPI from Nick, can't go wrong with the price. Even if you aren't going to rebuild your engine, MPI would be a better choice. I'm not very argumentive here as I am not stating reasons why the MPI is better, but from researching it throught multiple threads on this forum, I have easily concluded it is better. I also maybe slightly biased since I work 10 minutes away from Nick and he's the one that's doing all the work on my car.

haha the boots are jokes, dont understand girls, she had to buy them in the middle of august. i told her to throw them on for the pic since we wasted half the day going to get them.she sorta looks like a FF character or something with that outfit on in person lol. thought it was a funy pic so i posted it in my sig. /threadjack

I understand the added flexibility of the MPI in terms of fuel and injectors, but as far as spark timing only: is there anything that a J&S alone can't do that MPI+J&S, or MPI alone could?

 

[jeffmsp]

constantly advance individual cylinder timing to the max on the fly safely. Its a nice way to not blow a motor.

Which system does that?

 

[mazdaspeed75]

mpi

Mpi all the way . I will stick with this when i build my motor too. Havent had any probs I control my stock injectors and the extra injectors with no problems . Plugs look GOOD . I still pull more timming than i think i should but hey its still toghther . Rich wanna run (hah)

 

[MPNick]

More people run the MPI then any form of ECM on this forum. It is also the only proven ECM for the Protge in my opinion. No one has made more power, run longer, passed state testing and the best reason is the support on this forum from its users.
