Stock ECU vs S/R ECU

[jesus45]

So i'm gonna buy a S/R ecu soon, I know there is a performance boost with a S/R ecu. I just was wanting to know more in depth about the S/R ecu vs a regular stock one.

Someone elaborate :wiz:

[simplicity05]

There are different model numbers on the ECU's. The golden egg is the NGP0. If you're buying just the ECU, be careful not to get scammed.

That's the extent of my knowledge on ECUs other than the fact that I know I'll be getting an SCT Chip at some point so it doesn't matter at all which one I have. I'm sure someone else can elaborate on this more than I.

[WillZX2]

I believe the S/R PCM is tuned for 91 octane

what PCM were u planning on buying? The Ford Racing S/R PCM (replaced the NGP0, not sure of the code) is crappola. A true NGP0 is hard to come by..Keep ur eyes open for the stock ZX2 LXQ1 PCM, it's the second best PCM for a ZX2 (including S/R PCMs) and much easier to come by. As well, you can pump 87 Octane, as apposed to having to pump 91.

[simplicity05]

Do you know what cars those LXQ1's are out of?

And the way I see octanes is:
10 gallons of 87 @ $4.00/gal = $40.00
10 gallons of 91/93 @ $4.20/gal = $42.00

Yeah I'll pay an extra $2 for better gas. Already raping me without a dinner, movie, and roofie colada first, so whatever lol.

Plus if you have a Fleet Farm around you, they give you coupons for $0.04 off a gal, so the good stuff's even cheaper. Plus 93 oct. Win win win.

[WillZX2]

not sure what year the LXQ1 was from..ZX2Guy19 would know, he has one and has sold a handful of them I think.

[DOUGIESTYL]

Haysoos, you hafta have a mtx tranny, and a 6-wire MAF for an SR pcm to fit your car . If you're auto or 98-99.5 you're wasting your time. There's a mod to get the SR pcms to work in the early Zs, as far as wiring, but I only remember that there's an issue. I don't remember what it was. I think it was something with the cooling system. Somebody chime in...

[simplicity05]

Any info on the LXQ1 Dougie?

it's a problem with the air conditioning actually, so if you don't have a/c you probably wouldn't have to worry about it. I think you still need to change the ccrm though too, but don't quote me on that.

[DOUGIESTYL]

^^ 2nd best.

[pissdrunx16]

Posted via Mobile Devicehe is talking about the xhg3 s/r ecu that I have..... Yes must have a 6wire maf and a manual to work I have heard about lxq1 but not much... I have stock edu lxq2 is sucks but I am getting that ecu SCT'd out lol

[simplicity05]

Sct Ftw

[jesus45]

So which ECU do i want to avoid, and which ones are ok ??

[pissdrunx16]

Posted via Mobile Deviceany s/r ecu is good besides gsr0 or what ever fords upgrade of of ecu's was(avoid) and lxq1 is ok...also from what I understand... Other than that stock is stock

[mellowness65]

lxq1 is a '00 and '01 pcm i think

[pissdrunx16]

and the only stocker woth a shat^^

[mellowness65]

i think lxq2 isnt far behind

[pissdrunx16]

I have lxq2 its deffinatly a no go..... compaired to my c**4 superchiped or what ever my old ecu was it sucked..... and compaired to my s/r i am currently running it blows lol

[DaviDawg]

i could be wrong but i clearly remember vit stating that ALL non s/r ecu's perform the same.

[pissdrunx16]

Posted via Mobile Device^^^that's what I thought

[DaviDawg]

when it comes to ecu's, id take vits word over anybody else's.

[ZX2guy19]

The LXQ1 comes out of 2001 5-speeds. I sell them when I get a hold of them for $125 shipped priority USPS. They are better than CWQ3 and just slightly worse than NGP0, but cheaper than both of them and you have the option if you are low on money to put 87 octane. It is what I run in my car and I love it.

[TanyaZX2]

If all S/R PCM's perform the same then how does the LXQ1 Dyno higher then the CWQ3 but lower then NGP0?

[DOUGIESTYL]

Um. All SR pcms DON'T perform the same. The NGPO is the first and best.
Which pcms came in 2000s? I'm going to look at buying one, and I'm gonna check the PCM, first.

[4U2QUIK]

WOW sooo much misinformation here.

[DOUGIESTYL]

???

[xtremecaraudio]

WOW sooo much misinformation here.

yeah, would be nice if Vit would get his ass in here and clear some of it up. He's looking at the tuning of pretty much all the different ECUs and could clear up a lot of the BS.

[Kilroy]

Yeah, someone should just delete this thread now, there is so much wrong information/assumed information in this thread...

[ChillinZX]

I like my LXQ2. Dynoed 107whp 112wtq stock.

[Onespeed]

Bummer... I just checked the sticker on my door and it has gotten wet and is unreadable.

Any other way to find out what tune my car has? I will need this when I order some custom tunes for the XCal2.

[pissdrunx16]

yes you will need it I thin there is some other place on the car that you can read it from other than the passanger door jam...... if you cant find it, it will be on the ecu itself.... take the two screws outa the back half of the consol (one on each side) slide it out... then undoo the two screws infront of the ebrake on the upper half of the consol.... take of shift knob and two plactic pins on each upper side of the upper half of the consol.... walllla under your cubby should be you ecu and its printed on the front and the back of it.....
and you will need that info for the xcal

XHG3 and CWQ3

[Kilroy]

My XHG3 is pretty nice in my opinion and I've also had 93 octane burns on an SCT X2, so it's not like i'm just saying that because I have it. =P

[pissdrunx16]

i have a xhg3 it was awesome compaired to my CIL2 with superchip... but the xcal3 I just got today with 93 octaine tune is awesome!!!

[DOUGIESTYL]

The one I'm buying is CWQ3! I convinced the dealer to let me pull the console! I'll get to pick it up today, as long as the finance numbers are acceptable.

[pissdrunx16]

thats a good deal then.... at least you are buying a car with a decent computer!!!!! i had to hunt for a decent computer when i got mine lol

[xtremecaraudio]

hopefully the dealer didn't decide to flash it. they likely ran a diagnostic on it and noticed there was an update for the computer (all s/r codes have an update that evidently sucks). May want to drill them a little bit more on that if it is a selling point on the car, and no, they won't be able to flash it back if they already did it.

[pissdrunx16]

yeah the update sucks haha

It was a Hyundai dealer. The dealer didn't even know there was anything special in it. They basically just cleaned it up. No service. The drive home proved they didn't F with it. The alignment's a little off, and I gotta do a brake job. No biggie, tho. I'm gonna be in this sumbitch, turning wrenches, ALOT! (mods)

[xtremecaraudio]

Good to here it wasn't Ford, they probably would have fucked with it.

[Beodude123]

There are so many different stock tunes, that it's hard to really say which is better. LXQ1 (stock tune) vs GRS0 (99 S/R update), and LXQ1 will win every time.

Just get a chip dude, it's way better. Plus, if you have an ATX (not sure what you have), you can't use an S/R PCM anyways.

[Kilroy]

half of us are probably running around with S/R ecu's that have been flashed and we don't even realize it! It's all in our heads! =P

[pissdrunx16]

Posted via Mobile DeviceI am sure mine isn't flashed since it runs better than my stock/chiped ecu!

[Ank58]

I was wandering what all the different pcm calibrations are out there. I think i saw somehere a list of them but I dont remember where it was. I was thinkin there were even some that never made it to street production.

[dareall]

this should help out a little

[dareall]

i could be wrong but i clearly remember vit stating that ALL non s/r ecu's perform the same.

the only stock ecu's that were different than the others (excluding the s/r) are the 2003 units. Ford SUPPOSEDLY recalibrated them to have 5ft-lbs more torque than previous models.

[Boss122]

Actually, that's a misprint in the sales and marketing literature. The 2003 models have the same HP and torque as the Non S/R models in the previous model years.

[Boss122]

The best S/R PCM to get is the CBT5, but they were nto a production item and I don't think they are available any more for the dealers to flash to the PCM. The man that did the S/R PCM programming at ford on an engine dyno did the CBT5 as an off road use only S/R PCM for ZX2's and S/R's with a bunch of bolt on mods. In the end, a well programmed SCT flash or chip with some dyno time for tuning should get you similar results as the CBT5.

Wow, you should delete your post since it is full of shit. The 03's are some of the worst do to them trying to cut emissions even more. Like Boss said, it was a dealer misprint.

[dareall]

Okay, maybe I should have stated that Ford supposedly recalibrated the 03's to have 5 lb-ft more than previous models.

You two can now unbunch your panties from your ass cracks now.

why do we need to "unbunch" our panties when you are the one who doesn't know what the hell he's talking about?

[mechtech]

Take it easy - Ford made the mistake and perpetuated it.

[R-Code]

LXQ1 is from 2001

NGP0 and JHJ0 are the 2 best

XHG3 is NGP0 with 3* less timing, and CWQ3 is JHJ0 with 3* less timing (for the most part)

GRS0 is XHG3 with a few more changes to make it weaker and QLU0 is CWQ3 with the same changes.

I havent seen CBT5 so I don't know what it looks like.

[Kilroy]

is anyone near pittsburgh with an X-2 that can check to see if my XHG3 was ever reflashed by a dealer? I'm not sure if you can tell just by plugging into it with the X-2 or not, but just wondering...

[ChillinZX]

LXQ2 is 2002, I had no complaints about it.

[pissdrunx16]

Posted via Mobile Devicemy lxq2 sucked no so much any more wiith the xcal

[ChillinZX]

Mine dynoed pretty good bone stock around 109hp

If the pcm was reflashed you would have a recalibration sticker under the hood.

[Kilroy]

really? where at?

[TSmiley98]

WOW, thats all I can say , we have misinformation, buddy fucking and everything else in here,

Vits dyno charts show the NGPO, LXQ1, CWQ3, as teh top three in that order,

yes the LXQ1 is a 2001 ecu, forget about a JHJO you will never see one,

As for paying a ton of money for an LXQ1 I am going to be nice for once and let EVERYONE know, not just people I like, that they can be had for $40-$60 SHIPPED where that is for you to figure out

Has he ever dynoed a LXQ2? I don't think so.

[TSmiley98]

your right he hasnt, because he chose that one by the best looking timing and fuel mapping compared to the NGP0,

[pissdrunx16]

Posted via Mobile Device either way lxq2 isn't much greater than a stock!!! That's first hand!!

[R-Code]

The dealer doesn't ALWAYS give you a reflash sticker on your hood, but they should.

[pissdrunx16]

yea whatever sct ftw!!

[Kilroy]

The dealer doesn't ALWAYS give you a reflash sticker on your hood, but they should.

okay, well back to my question then... who has an X-2 near pittsburgh? =P

[R-Code]

that wont really help much, the better identifier is if you unplug your knock sensor then log the borderline knock at WOT, that will help ID which it is by looking at the tables.

the xcal wont say "NGP0" when you plug it in, it will give you a long strategy number.
