Just finished my s-trim install yestaurday. I put in 42lb injectors with a matching pro-m meter. It idles like shit, very rich, but when i'm actually driving it runs like a champ. Do you think my computer will learn to run better with these injectors or do I need a tune asap? Thanks.

Anything 42# and up needs a tune to compensate as the injectors are too extreme for the stock EEC at this level

You should have thought about that before the install. There is no way you can run 42's on a stock computer w/o a chip.

yes, but you'd still need a tune with some sort of programable chip or tuning device to compensate

You can run up to around 50 lbs injectors on the stock computer with a tuned chip. Talk to Byron at racesystems. I know the stock computer will not keep up with anything bigger than 50.

Well whether or not you can get 36 # injectors to run on a stock computer really depends on your combination of parts and ECM. I've seen a few cars which are able to pull it off and others that cannot. It really comes down to how well your MAF is calibrated for your given combo. Also how well a person is able to tune other areas outside of the computer. The mechanical things such as tps settings, throttle along those lines. Like I mentioned before anything that carries 42#ers and up is almost surely going to need an on board chip or pcm flash to correctly run. A combination featuring 36# injectors certainly has driveability to gain with an on board chip or pcm flash as programming tailored to your particular combo will always turn out the best results. Even with a finely tuned MAF there is almost always room for improvements through tuning at the 36# level. 42# injectors is really the cutting off point for high impedence injectors. A stock pcm is programmed to run on high impedence injectors. At the 50# levels most injector companies switch from High to Low impedence injectors which isn't as simple as a common chip tune. At this level either the pcm is re-flashed to except low impedence programming or there is an inline box with takes the low impedence signal from the injectors and converts it to high impedence ahead of the pcm. I believe the company which sells this inline box is located here in Pleasanton or this is the location of a distributor selling such a product.

Theres other places but they use different software. Dyno labs in San Ramon is one which uses SCT tuning software

I keep hearing about this place. My question to you is (and sorry about borrowing your thread man) if they're using different software, what is needed chip wise? Not an autologic chip I'm guessing? ![[Confused]](confused.gif)

Ray uses SCT software which is superchips. This would require a different chip than an autologic. As far as results from this place I can't say for certain since I've never been there. I am meeting with Ray tomorrow to discuss some business and I should have a feel for the place at this time.
EDIT: I can't confirm that an autologic chip will not work here just yet. I have heard Mike Westley from chipmaster (autologic) may have teamed with superchips to release this SCT software which may feature autologic style chips. Will keep you all posted as to what I find

cool, thanks mike. I'm interested to know more on this software and tuning, so please....as you find out more report back!
I think with the aftercooler and a couple very other small things it may be time to go back for a nice summer tune.

Hey. I just talked to them. It is $599 for everything. It is extra if you want more than 1 tune. But the 599 includes everything but tax. Seems like not too bad of a deal and its a lot closer for me than anywhere else.

Get a PMS for 400 more bucks plus you can change it all if you change set-ups for as long as you want and however many times you want.

Does that include a 'courtesy reach around'?

I think it's 499 unless it just went up this week...
The good thing about Dynolabs is that the tune throughout the entire week, not just on weekends.
I called to make an appt on a friday and was in the next tuesday. ![[Big Grin]](biggrin.gif)
