Performance Chip help

[MarkD]

what? no way. there is no way an off the shelf chip is going to be better than a fully tuned custom option (MS or otherwise), from a performance perspective. Of course you need things like a wideband if you're going to tune it yourself. You also need dyno time. When you buy an off the shelf chip those are fixed costs spread over many copies, but they do still exist. Just not in a "finely tuned specifially for your motor" form.

not to say that an off the shelf chip isn't a good option. But there's no way it's the best performance, unless you dyno tuned each car yourself. It's a very good compromise from a performance vs ease of use perspective. Plug it in and go. maybe that's what you meant to say..

This is a really late response to your post but remote tuning is an option and that is what I was referring to. I do quite a few of those and they work perfectly. Whether a NA motor is running 27 or 28 degrees of timing at some particular load and rpm is not as important as the AFR, and that does not require a dyno to adjust, just some runs on the road. I was not referring to a completely off-the shelf chip. I've been offering remote tuning for roughly 5 years.

Has anyone run a 2.5 i chip on a 2.7 Seta-i combo? Do you have dyno results?

Megasquirts or stand alones are definitely not for everyone. But if you are a gadget whore and a control freak who is constantly trying to push the performance envelope then its the only way to go.

It's over? You want to replace a well designed factory ECU with MS? I sure wouldn't unless there was no other option. On a stock motor with no FI, a chip works better than Megasquirt. I can make a chip work on a turbo motor also. Why is it that people mention MS or the other options, but don't say that you also need a wideband AFR to tune it properly? It's not the solution for everyone. Some people are not able install and tune a system like those.

well some people have developed pre-tunes....

i want MS but it depends on what peoples budget or plans for the future are like if i went MS i would most likely go turbo in the future and if i didnt want to go turbo and keep the m20 i would chip it. or chip a swapped motor

MEGASQUIRT! Thread over.

Thanks man, I had found that site but wasn't quite sure if it was MardD's website. I appreciate the help.

I've changed the banner on the main page to indicate it's my site. Look for the animated text that says:

Ok.Awesome explanation, thanks a lot. Im searching the most valuable info on those chip's to upgrade mine. Is a little bit hard to find a super-eta one but I will try my best. Thanks a million times.

A humble question here, why I need to run high oct if my car is shipped? Just to a proper function, to not break or just to deliver the expected hp and tq gain?

You gain most of your power from the way the performance chip advances the ignition timing. Higher octane fuel (91) burns more "slowly" than lower octane fuel (87) since it is more resistant to combustion. Since your chip advances the ignition timing, the air+fuel mixture is ignited before the piston reaches TDC on the compression stroke in order to get the combustion started. The goal is for the combustion to come full-on at the right time just as the piston is on its way downward on the power-stroke.

A lower octane fuel will begin combustion too early since it ignites more easily and the energy from the ignited air and fuel expanding is wasted, trying to force the piston downward when the piston is traveling upward.

Easy mode: The chip needs higher octane fuel because it is harder to burn 91 octane than 87 octane and the new settings with the chip would cause 87 octane to burn too soon and waste power.

I decided that Im going to stick with MarkD for now. I dont want to spend too much because I still need to buy wheels and a sound system.

Just double check, is anyone running the Markd with the 19lb injectors? What else would I need to change with the Markd chip?

[Acehye559]

BMW_318i and BMW_325i - thanks for the info. I looked at Miller products and only heard good things about them. However theyre a little pricey, I mean you get what you pay for. I was looking at their Miller Maf kit with the Miller chip and really interested. But I also know another member here (Castro) has similar kits for a little cheaper. His kit works well with larger injectors. So really got to do more research and see which one is worth getting.

Sorry - didn't mean to be a smart ass there.

Google has a search function too..

No need to change the FPR. Honestly you aren't going to see any gains swapping injectors, the stock ones are adequate unless you have upgraded everything else in the engine. The only advantage of mustang injectors is that they are a newer four pintle design and have better atomization.

Depends on the injector. I use 19lb from E36 that need 3.5 bar for that flow, paired with a MarkD chip. For a couple of months i used the stock 3 bar fpr and there was mild pinging from 5k rpm at WOT.

Recently put in an IE adjustable and pinging is gone.


Agree that they are overkill for stock engine, but if current injectors need replacing, and upgrades are on the horizon then they would be worthwhile.


Acehye559 - seriously consider the Miller option. I've got a MAF and 19lb ECU on the way as my AFM is not 100% anymore. In the long term their WAR chip is an upgrade path.

But then, if you go turbo or serious mods then 19lb may not be enough?
