Hi all, i'm a noob when it comes to MINIs , all though i admire them. I've been reading up on the forums and have come to the understanding that an ECU chip will have virtually no effect on an MCS with a 19% pulley upgrade. I might be wrong in my conclusion but that is why i am asking u guys. What effect will an ECU chip have on an MCS with a 19% pulley upgrade, besides the obvious higher rev limiter and speed governor being taken off.

Thanks in advance.

You can always squeeze more HP rom an ECU upgrade, IF it's done correctly.
Simply consider that the fuel mapping alone would be different much less timing and other factors.
So yes a well done ECU will get you more HP that using the OEM mapping.

Ok thanks for ur input. Another question related to the topic, would it be possible to boost an MCS to 220HP and 210LB/FT TQ from a BMP/ProMINI air intake, 19% pulley, ECU Chip, and a custom free-flow exhaust (exhaust would be 4-2-1 Header/Exhaust Manifold, No Cat or Race Cat, and end up with dual tips, not in the centeras normal, but on the outsides, like the E46 M3 has for example.) The Reason i say custom exhaust is because i wouldn't have enough cash to dish out on a miltek header and supersprint catback exhaust as that would cost over 1g and a "custom exhaust" that is virtually the same as that would only cost me between $300-500.

I think it could be achieved seeing how Promini claims 13hp and 12lb/ft tq from the intake, 19% pulleys should boost up 20+hp,lb/ft tq, milltek claims 12hp from there header and supersprint claims 5-8hp from there exhaust (i use those 2 because the custom exhaust would be almost identical) and a properly tuned ECU mapped for maximum performance should give an xtra 5-10hp with those mods. But once again i am new to the MINI and don't know if theres anything else that would need to be done in order for the engine to safely produce those numbers.

Once again, Thanks in advance.

who wants an MCS

I have just installed a 15% pulley (Sunday) after being at the Rockford MINI meet and watching/listening to the venders. The universal advise given was NOT to do the 19% UNLESS you are full race. The heat output and preventions needed to off set that out weigh the small HP gain over the 15%. They all suggested the 15% PLUS the mods that you mention. Less hazardous and less expensive. I must say that with the 15% and a K&N I can most deffinately tell the difference. The exhaust is next, a chip maybe later.
enjoy

I recommend you read the following post regarding a 19% reduction pulley and ECU chip:

http://www.mini2.com/forum/showthrea...831#post937831

Also, when it comes to performance upgrades, the total horsepower and torque gain of the whole package doesn't equal the sum of the performance gains from each piece

BTW, the ProMINI intake doesn't produce the gains claimed on their site ... more like 4-5 hp.

[obehave]

Agreed with MINIAC.
Performance upgrades are not additive. Optimistically you might see 200+ a few.

There are also some claims of 30+ HP from just an ECU remap. They may or may not be substantiated independently soon. We'll see.
Do your research like you are here and you'll dp well with your money.

I agree performance upgrades are not additive. But i'd say that when all the upgrades have to do with the same thing, it would be safe to assume the numbers, although not exact, would be close. In this case all the upgrades mentioned have to do with how the engine breathes. All input is appreciated.

Hi Guys,

Ok o3MCS asks if 19% pulley + chip + no cat/race cat + free flow exhaust + induction kit will give 220 bhp.The replies seem to say that maybe 220 is optimistic.
Yet two 'well known tuners' claim almost this figure with just a pulley and chip.IMO Something just does not add up.If the latter is correct then o3MCS should be getting at least 235-240 bhp.

That would be why I said

Seems you agree yet disagree
First you have to believe all those HP claims are 100% accurate.
Basically all major performance gains deal with engine breathing so your argument doesn't really stand up based on that.
Simply put all MINIAC and I are saying is you can't just add the HP claims for each mod and that will be your total gain. It doesn't work that way. Never has and never will.
That's not really debateable.

Saying it will be close is too vague really. That's why I'm not saying you will absolutely get X HP out of those mods. I don't know. Even though I have most of what you're talking about on my car. (No race cat)

If you also add to the mix .. High flow fuel pump, set of oversized injector and a optional larger Throttle body.I think its achievable. This being of course since im already running the Induction+ Tunable Free flow exhaust+19% pulley+modified Cat. With chip / SAFC2 in the works as soon as Hubie from SPI sends me the diagram on how to wire it up. I should be in the 220+ area. in a thread about the Twin Charged MCS i believe JLM also with all the mods listed above including reworked SC and Head. done by "The old ones" pulled a dyno of 200 whp which equals to the 240-240+ bhp

just thought id add my 2ctw

You need to make this your sig
" With chip / SAFC2 in the works as soon as Hubie from SPI sends me the diagram on how to wire it up"
You've been waiting for that longer than I've been waiting to get my UNIchip back

[roland2003]

Hi guys,
obe To be honest I'm inclined more towards your opinions/guesstimates anyway,which means it's the 217&218bhp from pulley plus chip I find hard to swallow IMHO of course!

Roland what tuners pulled 220hp from a pulley and chip? I'd be interested in reading on their work.

[roland2003]

HI 03,IIRC West tuning &BBR. (217&218bhp)

[Mugami]

Obehave. I would add it to my Sig but im at the limit now according to the Mini2. lThen ast update i got from Hubie.. was that the details of his Turbo package was to be ready by the end of June. Which has the diagram of hooking up the SAFC2. im giving him two weeks then calling back up there on July 14 to get the next update. I'm a very patient guy as you can tell. I've call APexi again and they have nothing . Also Mini and a few local tuners. Hubie is my only chance of getting the diagram of which wire i hook into. I've already ordered the 370cc injectors, High flow fuel pump, Ik 22 plugs and set of Live wires. With a possible Dyno Day coming up on july 21-23 in Fairfax, VA i would love to have it ready but i'll be ok with just the stock settings then showing what the difference after the SAFC and all of above is installed. Oh of course ill post the Dyno sheet once i get back.

Very cool.
Hope you get it all together soon.

Yea roland, I'm just ahem.........hard to convince
Believe me I'd love to see a confirmed 30+ HP from an ECU update. Me and about 200 other people

roland, does west tuning have a website?

mugami, can't wait to see those results

obehave, yea i'd like to see that 30+ gain in person as well, but unlike you i just give people the benefit of the doubt on claims like those...
------not being a by that comment btw------

[Bisch]

Mugami,
Who/what/where on the fuel pump and injectors? I'm at that point....

[Mugami]

There are different Fuel injectors out there some perfer Accell. etc. for me I've used RC engineering Fuel injector for a while now in my race car. and since he has the Bored out Throttle body as well im getting the two as a kit. Also will get the Fuel pump from his recommendation. I've yet to see where someone switch from a 330cc injector to a 400cc one where you didnt have to switch the fuel pump so im taking it as a given i have too. Other thing is to call to SPI power excel 1-732-290-2213.. My friend Hubie who's the one comeing out with the twin charger kit for the mini and see what he recommends.
