Big head man
|
Well I have to say thanks for all the help to Phil and Kris. With a combination of new maps and hints from you both, I've got a great base tune now for the car, a steady idle that doesn't stall with the a/c on, an extremely smooth second cam switch (with my car and map we chose 4800 RPM), no oscillations at idle and so far no problems with reverting back to the less aggressive cam when I don't want it too. The next step, if I want, would be a dyno run with more precise adjustments.
I'm a very happy man right now. ![]() Thanks again. ![]() ![]()

It is great that Phil and Kris are helping us out. My car is running smoother in terms of throttle transition -- will know exactly how smooth after this weekends event at Thunderhill. Unfortunately I still have idle oscillation and stalling on the street map -- haven't tried the track map yet so I may need another visit to FF.
However, progress is being made and that's what this is all about. I feel confident that Kris/Casey can get everything fully sorted.

And as for my EFI tune, still running fantastic. Ran 2 hard hours out in the country last night, what a blast and ZERO issues. Currently putting out 250WHP/160TQ, with loads of advance still in the bag. All this without any formal power tuning yet. Not going for the all-out here, and still should push a conservative 260+ with the 3.2" when done. I have a tuning session scheduled late September on a load bearing dyno to dial the maps in tight. Kris has been a huge help to me as well, and with the logging option installed, he can get complete data on my car in minutes via the internet...it's just too cool. If you want a solid self-tunable solution for the Elise, this is it.

GReat news on all the above...
I mean it truly is fun to tinker with these tunes and continue to find way to safely tune our cars to perfection. Everytime you change a part on the car, whether it be a TB, airfilter, muffler, headers, boost, etc, you're changing the volumetric efficiency of the engine which means that you should/could change the tune to further perfect the pwer band of the car. While that fine tuning doesn't have to be done, you now have the option to do it. For me, it really helped to justify spending the money bolt-ons since I can now tune for them at my convenience ![]() All this talk makes me want to go out and drive the car with the new intake a built for it 2 nights ago.... oh ya, and it doesn't have a MAF sensor to clutter things up so I was completely unrestricted in the type of intake I built (Not as fancy as Jim C's though- very nice Jim)... Why, becuase I can with the EFI! ![]() Best, Phil

Good to read the positive stuff and not just some clown mindlessly slamming someone that dared to take a different path. The EFI and Kris @ DRS worked well for our purposes.

Now you folks are making want to get this for my IQ3 ($359.00 - ouch) and start tuning
Problem is, I don't know jack about quality tunes, but hope to learn.

Casey, I'll get one if you teach me how to use/tune it.

I'd like to suggest the NGK AFX. Great little unit. Darksol and I both use it... HAs a display if you want to use it and it is it's own controller. Works great with EFI and that same output can be used for your new dash project to display AFRs... Best, Phil

NGK AFX MSRP is $700+, but you should be able to buy one for about $340.

ngk afx - Google Product Search
Looks like they can be had for sub 300 or so... I just used google or ebay to buy mine...can't remember which one, as I've slept many moons since then ![]() Very reliable, robust, and easy to use... Best, Phil

From what I can ascertain from this thread it seems that some people might have this EFI ecu installed on their street car.
![]() ![]() However, ecus like EFI and Motec are for off-road/track use only. Do terms such as legal, OBDII, CARB, and drivablity ring a bell? EFITechnology I'm all for race application standalones as they circumvent all the OBDII limp mode nonsense. And that is why no one has taken Grand Am up on their 200 pound weight savings for running the stock ecu. But to promote this towards street applications is not wise nor ethical. ![]()

BTW- Got new dyno figures today. Did just smidge of fuel tuning after installing intake... stay tuned... ![]() Best, Phil

Dyno Plots
Ok- I had about 45 minutes to buz up to the dyno today. I built a simple intake which is simply a KN cone on the end of a 3" pipe with a bracket. No provision for MAF, since we don't need it... I wanted to see if the new intake made for any add'l power and/or leaned the car out... Wow, it makes a nice difference! It should be noted that my last dyno with the stock box also had a pretty dirty green filter, so this may not be a super fair comparison...
Of the 4 plots to follow, The first one shows the pulls before and after I tuned for the intake. Notice the AFRs. I added about 5% fuel to the tune which brought the AFRs back to where I like them... I also posted up another few graphs comapring the EFI tune to a Darksol's car which has bolt on mods similar to mine, but has the Katana tune. I focus my tuning or torque, so I posted a graph up comparing the TQ. Check out the vertical cursor on the graphs indicating the hp/tq/AFRs throughout the run. 15ft/lbs more torque through much of the rev band after cam switch Also Notice that I only rev 2 8300. When I'm at 8300 (my redline), I'm at 241whp while the Dave's Katana is at 224whp... He continues to rev till 8500 and runs to about 230whp... 200 more revs on my car may have taken it to about 250whp all the time while running a "safer" AFR... Tuning isn't for everyone, but if you're interested in learning more about your car and taking complete advantage of the add'l volumetric efficiency of your bolt on mods (headers, exhaust, intake, etc), tuning can be quite rewarding...Thought ya'll may find this interesting... Best, Phil

Oh ya---
I forgot to post this graph. This shows the gains from before and after the intake after I tuned for the new intake... THis is really neat

I guess the point is that there's plenty of ways to get around smog regs, as people do it all the time... Every car community I've been part of contends with it...
The above dyno's are enough of a reason for me to deal with it when it comes to KS , as it's on the horizon ...Cheers, Phil
