Received my Dali chip

[vandale]

Hello all,

I installed a zip socket and my Dali Super Chip today, is there anything I should do to run it in?

How long does it take to remap the fuel etc?

Should I see an immediate performance increase?

How do I know everything is ok, do I need to get it dynoed?

I have headers, exhaust and k&n filter.

Regards

Gene

You can reset the ECU by pulling the clock circuit fuse under the bonnet (although this was done by removing the ECU from the car to solder in the ZIF socket).

It makes sense to have the car's new tune verified by a dynometer, to confirm a safe AFR - it would make more sense to do this after having done a baseline run with the factory software.

1.) Do whatever the poor Dali instructions say to do. Most likely, if you screwed something up, or if you did everything as per the instructions but the instructions are wrong (not outside the realm of possibility, I can tell you that), then the car won't start.
2.) The performance 'increase' should occur no later than 1 fill-up. Probably a few miles and some pulls but to be safe, you can give it a fill-up or so..
3.) Butt dyno should say yes, especially if you start with low fuel and a little sprung to begin with...
4.) You should get it dynoed for one or the combination of reasons:

• To get mad when you find out that you did not make any power, and may have lost some.
• To be happy when the dyno shows +2.5 HP, WOOHO!!
• To rationalize if a happens and say, "screw physics and mathematics, it feels faster, woohoo!!"

4.) Welcome to the club. I have AEM, check :tongue:

Well I reset the ecu and put the factory chip back, went for a quick drive on the motorway and then pulled over and swaped them out, reset the ecu and went back onto the motorway. Did a few 0-9k in first, second and third gear. I then drove around wee bit, filled up with 98 Octane and went back out.

It made a difference and the rev limiter has moved which suits me as I was always hitting limiter in first. :smile:

Vtec comes in slghtly earlier, not sure if this makes any difference. I will get more accurate results when I do a few 1/4 mile sprints in the coming weeks. It will be interesting to see the results.

Cheers

FWIW, moving the redline to a higher rpm does not increase the horsepower or torque of the engine. The redline is set at ~8K rpm to protect the engine internals from damage.

I have done back-to-back dyno pulls with three different after-market chips and found the OEM to make the most horsepower and torque.

Yes I understand that, I like the extended rev limit as it suits my style of shifting.

I have done many searches and read alot of info on the chips available for the NSX, I understand some people get good results, others get bad. Some data records show increases and others decreases. The only way I will know for sure is some dyno runs in the near future.

Thanks for the info.

You should not be running around with 9,0000 RPM rev limiter. Let me repeate, you should NOT be running around with 9,000 RPM rev limiter.

Possiby 8500 RPM is ok, 8350 yes, but 9000 RPM, this isn't F1.

OTOH, it would be great if you can record how the car sounds when it blows up if you do maintain a 9000 rpm rev limiter.

I think the dali chip allows a 8300 rpm fuel cutoff.Either way if your heads are stock the motor can not take advantage of higher rpm for more anything.The efficiency as an air pump is limited by its design.If you do wish to "overrev" the car I would invest in a billet set of oil pump gears.

This is very good advice.

If you do wish to overrev the car, I would put 20k in a short term CD.

Thanks for the advice guys, I will take it and move forward.

8300rpm suits me fine.

You're welcome let me know which cd you choose, I'm shopping around myself.

I doubt any aftermarketers did better R&D than Honda. Dali probably sold you a dud just to get your money.

They probably just copied the OEM program onto their own chip

Classic post !!! LMAO:biggrin:

The way I see it is that Honda would have developed the fuel map etc to suit an un-modified C30a. The aftermarket chips are designed to make use of free flowing exhaust, higher octane fuel etc.

If I search SOS, Dali ECU's I find lots of Dyno results that led me to believe that the chips do work for modified NA C30a's.

I have wanted to Dyno the car and this will just be an added bonus if it does come up with more power.

i've been running the dali chip for a few years. i can honestly say that i don't feel like it does much. i may have an older burn, but i'm pretty sure the rev limiter is set at 8.5k rpm's. i gained a tenth in the quarter mile with it ... that's about it.
i wound up taking the dali chip out for smog (put the oem chip back in). never bothered to reinstall it.
oh yeah, my engine never blew up. just don't drive down the road bouncing off your rev limiter for an hour straight. :wink:
