From what we've seen with others, the stock chip overfuels most of the time with 550cc injectors. I can also confirm the overfueling, since my car barely passes California emissions testing and has fuel economy significantly lower than what others report. Plus, the finer control of onset of boost afforded by Alan's chips should make driving the beast easier.

I'd buy one, too, if Alan had such a chip available. Heck, I'd take my car to Alan except I'd get really damp driving it there. :wink:


I agree. I like the idea of an ungraded turbo and injectors but not without a properly mapped ECU. Otherwise its all guesswork as to whether the engine is running at peak efficiency, power output and not exceeding any safety margins. If Alan was able and inclined to create a chip for this upgrade then I'd definitely do it.

Yep, in an ideal world it would be best to have a Chip design for this upgrade but this isn`t available and i don`t know if Alan has even looked in to this. The other option is to replace the ECU but thats a costly affair and something that Dico and I will look in to if a chip is never developed, But for now i think it`s been proven that 550 injectors, 3 bar map, and EBC works well, but obviously won`t be running at it`s peak performance compared to an programable ECU.

Anyways it`ll be Dico`s that`ll go pop 1st LMAO :-D

I'm reasonably sure Alan has looked into it - we've exchanged several PMs on the subject. His biggest constraints are time (like all of us) and especially not having a car from which to pull useful data.

I emailed Alan about the update stock chip for Dico and did ask him a quick question about the Chip for the Garrett upgrade.

His reply
For the garrett turbo version the thing I really need to figure out is how the fueling code works. It's not easy (understatement) but it's not a hopeless cause either. Be patient, I'll spend some time on it over Christmas.



So there is still hope there :-D so for now anyone thinking of going to an aftermarlet ECU should hold on.
I`m just thinking maybe Dico should just use a bleed valve for now and a decent boost gauge rather than waste money on a EBC when the money might be better of going to Alan if he can do a custom chip :?

I'd definately be in for this - a single switchable chip would be the neatest solution.

I guess I'm going to have to change the boost gauge too!

i assume that by EBC you mean electronic boost controller?

that being the case, let me inform you about the unfortunate effects of installing a 3 bar map with larger injectors. the voltage range from the sensor is the same, but the amount of pressure (boost or vacuum) is not the same as OEM at equal voltage readings, which leads the ECU to think that boost is lower and timing gets highly advanced causing detonation, leading to cracked blocked and chipped pistons under larger loads.

if you are going to run more boost, you need to be able to control timing. please be careful! the stock ECU is plenty capable of supporting 12 or 13 psi within a safe margin and moderate level of performance. don't blow up your car over a 3-5 psi. drive it like you stole with 12psi and when your ready, upgrade all your fuel system and ECM together. that gives you time to let others develop a properly tuned mapped which i am sure they will gladly share :wink:

in fact, i have recently purchased a Haltech and expect to run 22psi on a dual stage EBC. i should have it installed this spring and tuned by end of summer. i will gladly share that a/f fuel map with anyone interested.

i'm starting to get bored of the 12psi and refuse to run an A/F controller without timing abilities, i've only got a SAFCII laying around. i got my haltech, 450cc injectors and a 3 bar map for later.

i'm also installing cams:

intake 218/.350" @ .050 lift
exhaust 225/.350" @ .050 lift

i'll be installing them before the haltech upgrade. is anyone interested in the results of the cams? maybe some video?

for the price, i figured it would yield the greatest power increase than say nitrous or a larger GT series turbo.

Yeah, why not :-D


How come you went for the 450 injectors?

they were free! :D also, the stock 322cc have handled the 12psi well, even ran pig rich with ratio's as high as 10:1 under WOT. so i fugure nearly 50% more fuel and the adjustable fuel pressure regulator should be able to compensate for the next 8-10 psi of boost. next step will be to upgrade the fuel pump.

update, getting a Gtech Pro to test the upgrade. i'll post results later of the cam upgrade and then after the custom intake manifold.

CAMS going in before august 13th b/c Robie the Robot is coming to help tune the HALTECH. also in the works:

BOSCH 255lph fuel pump
450cc injectors
3 Bar Map
Custom upper plenum built off secondaries
Rodeo Throttle Body (0.200" larger throttle plate and sensor interchange)

very nice plenum.

you may want to look into the way air distributes itself through an opening on the front of a manifold. I have a feeling 1 and 2 will be running richer than 3 and 4 with the throttle on the end like that. most plenums of that style employ either a diffuser plenum, a tapered plenum roof, or a throttle body that is 90* from the direction of airflow into the inlet ports. food for thought. but that ought to be better midrange and at the top end than the standard piece

thanks! :D

i assumed that under boost it won't make a significant difference since the intake system will be pressurized. it's more a project of mine to make something else unique about my setup and hopefully it pays off. otherwise, i'm moving to a 1.8L manifold without secondaries and the RODEO TB.

looking at the edlebrock designs for like honda B-series, the plenum expands past the TB with the air flow in line with the plenum and perpendicular to the runners. in my case, it will expand a lot past the throttle plate then transition down the plenum. we'll have to wait and see :p

I hated the 1.8 intake, lost a bunch of power between 3500 and 5000. Nice looking manifold BTW.

really? wow, figured the power loss would have been lower, since the secondaries were removed. i'll have to run a itouch dyno and see. no access to a real AWD dyno in my area less than a 2 hour drive.

anyway, on a side note...i only got a partial run in, but the itouch/iphone dynolicious app read me a 222whp @ 12psi. the car weighs in at 2900lbs even with me in it and a full tank of fuel. i'll try and get a complete run in before the end of the week, because that's when i do cams :banana:

It's velocity, it does the same thing if you just leave the seconderay's open, huge hole between 3500 and 5000. Now the funny thing, on a 1.8 the 1.6 intake dosn't
give any advantage. Never could figure that one out.

lol...this upgrade thread has basically become my project thread :oops:

got the cams in and they feel awesome. haven't done another dynolicious run off the iphone/itouch yet. i did notice a noticeable difference in the tome of the exhaust. video link below. overall, the engine seems to breath better AND the rear end of the car squats noticeably under acceleration.

the timing belt gave me a workout! i COULD NOT get the crank pulley off :evil: thank goodness i had the center timing cover removed when i rebuilt the engine, i was able to see the timing marks on the pump and crank gear :D

i ended up creating a boost leak somewhere during my enthusiastic test drive(s). i'll find that leak and do another HP run. the first run gave me an estimated 222whp on the current setup.

enjoy! http://www.youtube.com/watch?v=73LrEQzNPuA

figured i would post this here and not hijack LGM's group buy thread:

it's my LAST T25 adapter and LGM's old 2.25" SS downpipe elbow.
