Chippin

[Accord4me]

hey ive been thinking about ecu upgrades and ive found one that caught my eye what's your guys thoughts on this piggyback VENOM ecu mod

http://www.horsepowerfreaks.com/price/Honda/Accord/Venom/Electronics/Engine_Management_Piggyback

i dont know if its for stock aplication or heavy tunning, i think its stock apps though... it seems like a pretty good deal to me if it holds true...

if its a no go, whats a good ecu upgrade? im looking under the $400 range that will yeild some change, bird u said u love ur jet chip... have any more info on that?

[birdman]

Ive heard so many mixed reviews on the Venom piece.
Mainly the wiring burning out, or slight difference from before,but since you asked about the Jet ecu, here we go:
The jet ecu is tuned specifically to your mods, and Jet recalibrates your fuel map, so you get the fuel you need whether you accelerate or not. I can feel the difference even at partial throttle. I noticed a big improvement in low-end torque. Wide-Open Throttle is pretty impressive for just the intake/headers. The shift points feel much stronger/firmer. Speed Limiter is lifted. I highly recommend it for those with bolt-ons, because it actually draws out most of their potential, and you'r getting more of your money's worth:thumbup:

would it be different if tha car had turbo? cuz you said for those wit bolt-ons ???

Although Jet could tune it w/ turbo, Uberdata or Hondata would probably be more practical. On the other hand, your basic bolt-ons i/h/e definitely need some tune-age as well. The car may breathe better, but with tha fuel-map Jet provides, it will be tuned more for performance then fuel-economy which the factory intended. No matter turbo or N/A, the ecu needs to be tuned to support those mods.

so i can use tha Jet ecu...but something like hondata or uberdata would balance tha tuning for both performance and fuel-economy?

Actually, hondata or uberdata would be practical if your going serious like turbo or a high-revvin N/A set-up. Ive seen some graphs on a Hondata dyno-tune and saw a k-series civic get an extra 30hp in the mid-range rpms because of the n/a set-up it had. Fuel-economy is pretty much thrown out the door when performance tuning is involved. I haven't seen Jet do any tunes for a forced induction set-up yet. But I heard of many guys w/ bolt-ons go for them because they are getting more of their bolt-ons potential.

Turbo or n/a=Uberdata/Hondata more expensive

I/h/e/=Jet much cheaper/better value especially if you're not going serious on your engine mods. I think I might keep it like this w/ a 5spd till I get tired of it.

cool...but i was thinkin of turboing <---is that a word? haha...
i would like to see a tuned forced induction set-up by tha Jet ecu...do they have a website or anything to refer to?

Its okay. If you're going to add bolt-ons and not get turbo for awhile, the jet ecu will be perfect till then, and its only like $300 and only a 24 or 48hr turn-around. here's the website:http://www.jetchip.com/

i juss read this on there site...
"Programming includes extensive modification to air/fuel ratios, ignition advance and boost pressures for turbo applications."
...i guess it does work for turboing...haha...i'm kinda leaning toward tha JET chip now...haha

[AccordEx]

Yeah Jet is actually pretty good, somebody on Honda Tech had a F23A tuned with it and came up with some pretty decent numbers.

[AccordEx]

found it

Well gents, after trying all the eBay resistors, "performance chips", and even the JET V-Force module, I have finally purchased the Jones Electronics Technologies (commonly known as JET) ECU Reprogram package.
*This was performed on a 99 Honda Accord 2.3L 4cyl Coupe 5-speed with light mods (listed at bottom).

Once I found my Accord's well hidden, hard to access ECU, I packaged it in the box provided by JET and shipped it off at 2pm on a Tuesday afternoon via USPS Express Mail. It made it from South Carolina to Cali by 8am the next morning! JET flashed it, and loaded their custom programs and maps into my ECU, and over-nighted it back to me at no extra cost. I received my ECU from DHL Deliveries at 10:30am Thursday morning, and quickly installed it. After pluging the 3 ODB-II connectors in, I started the car and let it idle for 2 minutes. Then I cut the car off for a few seconds, and started it back up. After a short drive, watching not to go over 3K rpms, I cut the car off once again to save all of its programs. I've been driving it since that thursday (now Saturday) and the car seems to behave better and better the more I drive it. JET has made a believer out of me, and I have the track results below to show why...

BEFORE...

0-60mph---------7.62sec

60ft---------------2.42sec

330ft-------------6.71sec

1/8th mile ------10.26 @ 70.00mph

1000ft-----------13.35sec

1/4 mile --------15.94 @ 86.99mph


AFTER...


0-60mph---------6.94sec

60ft---------------2.42sec**

330ft-------------6.55sec

1/8th mile ------9.92 @ 74.4mph

1000ft-----------12.81sec

1/4 mile --------15.23 @ 94.7mph


** My 60ft time remained the same due to wheel spin incurred by the newly found power.

The actual numbers don't show much of a difference, and I don't have any dyno results yet, but for a $220 ECU package, the gains are undeniable. I am VERY pleased with the results and LOVE my new low-end torque when I'm driving around town.

Here's a list of the car's setup when the track runs were performed. Please remember this list is very basic, and may leave out several not-so-important parts.

- AEM Cool Air Intake
- eBay ceramic 4-2-1 header
- Custom 2.5" exhaust from header back

i just noticed that this is in the wrong section, read the rules people...

[Velocifero]

very impressive. Hondata and Uberdata always get mixed reviews. This Jet Chip seems have gotten overall pretty positive remarks. i bet this would open my car up quite a bit. but if my gas mileage is 23mpg now, i wonder what itll be reduced to after the tunage. does anyone know the average mpg loss after a tune?

[Accord4me]

thats a question for bird

[birdman]

Wow!! nice #'s w/ the jet ecu package. He probably would have better times, if he had better tires in the front. .71 sec improvement w/ the tune is pretty good for only having bolt-ons. Ok as far as gas mileage is concerned, if you don't floor it all the time, it shouldn't run you out fast. But knowing anyone here on the forums, you will be flooring for the first week constantly. hahaha. I was getting about 250-275miles/tank in the first week cuz I floored it every chance I could get, but now since I got all that flooring out of the way, hahaha, I get around 300/tank. I have an auto tho', the 5spd probably will be much better in that department.

[Accord4me]

hey i have another question to go with this, i want to get the jet chip, but i cant not have my car, its not a personal thin its just i need it to get around. so i was thinking i could search some junkyards and if i found a 98-02 cord that i could take the ecu out of that and then send mine into jet and put the other ecu in my car so that i would still run. would that work or are the ecu's car specific?

[Accord4me]

i soo want one of these now, i saw the dyno sheets on a 2.3 vtec and it boosted power from 153hp@6000 to 165hp@6000 the power band for the Jet ECU is atleast 10hp above the stock run from 2000 - 6500 rpm.... god, i need money now....

ahhh i just checked the sight and its now listed at $300 am i looking at the right thing?

Yeah, you can do that->get & use another 98-02 4cyl auto ecu, and send yours to Jet. Im actually using Benn2k's Jet ecu. His is a 97 accord, so its okay.

[Accord4me]

dyno sheet for the 2.3 vtec with jet

pretty impressive

why doesnt honda market their engines at the highest power? i see the stock run hit the advertised 153hp at 6000 but continued to 160ish at 6500, is that just because its at redline?

what about the ecu itself? will getting this Jet tune make getting and an upgraded ecu unnessecary? thats possible right? i kant find the thread i recall seeing that. going from P13 to ....whatever. since the Jet adjusts f/a ratio, thats exactly what a new ecu would do...i believe i answered my own question again.

Are you thinking of switching to a p28? Im not sure what you're asking tho' about everything else. I actually thought you had one already. Wow!! you missing out bro. I see you got the i/h/e already on there, and a tune will definitely wake that h22 up like a motha'.This is what I got from that hondatech.com thread: "JET modifies the stock ROM programming, basically telling the ECU that it when it builds the ignition/fuel/air maps and tables, it should go for best performance, while maintaining fuel economy and emissions standards".

how can it have 167whp at stock? we barely have 150hp at tha crank...???

[AccordEx]

That graph is fake and its in no way measuring the wheel horsepower. Also the F23A stock isnt making any more power after 6000rpm.

Maybe thats showing a F23A with boltons then with the addition of a JET Ecu...but it still wouldnt be making all that power after 6K anyways so, yeah, its fake.

[birdman]

Isn't the shifting @ 6200rpm? The stock numbers are definitely wrong. The gain in each point is probably accurate tho'. I don't know about the power all the way up to 6500rpm. Im going to have to test that when I get mine dynoed.

[AccordEx]

Yeah redline is at 6250-6300rpm

im not sure i think P13. ima try and look tonight at my ecu if i can get a hold of some tools. i keep getting mixed results when i did research on which ecu is best for the h22. i hear P13 is the best, but i hear its unchippable. i heard the P28 is best and has good support. but then i saw the P72 is even better, which is the GSR ecu, cuz u can control the IAB. the downside of the P72 is the cost. i looked a few websites, but most of the data i got was from CB7tuner.com forum. can someone set me straight?

I haven't heard too much h22's run w/ the p72. Mostly b-series motorswaps. The p28 is a pretty popular application now, since yah, its chippable and all. Maybe you should wait till Brian does his runs on the dyno on friday and see what a p28 can do before you decide. I can't wait to see the results.

[Accord4me]

yea i dont think its whp, i thought it was a crank test, but maybe the tester ran a correction formula so that he just pluged in the whp and calculated the % loss then added it back to make it a crank hp graph, ive seen people do it before, i dont know why you would though... ive also seen specs quote early F23 @ 153... I agree with the no power after 6k, my engine drops off so bad it makes no since holding the gear... speakin of gear holding, redline is at 6,300 but my fuel cut doesnt hit until 6,750 but like i said theres no extra power up there. my old 00 had its fuel cut right at 6,350...
