Jet ECU Reflash / A'PEXi AFC info!

[SiRocket02]

After spending some time looking around on the site for information on the Jet ECU reflash and whether or not an A'PEXi AFC would work (allowing fine tuning of the air/fuel and VTEC engagement) I made a few calls to the manufacturers. The results are as follows:

Jet Performance Computer Upgrade:

"Approx 14 hp, 17 ft. lb. of torque to the wheels from 1500 RPM to redline at wide open throttle." -direct quote.

$329.99 plus the shipping costs of sending your ECU to Jet. (Jet overnights the chip back to you for minimal downtime.)

The ECU is reflashed to maintain drivability. The map is tuned depending on the modifications to your specific Ridgeline. Timing will be tuned as well as air/fuel.

*Other air/fuel controllers such as the APEX'i AFC-NEO can be used to fine tune the air/fuel to your truck as long as the unit does not further change settings to the timing of the vehicle.

APEX'i AFC-NEO:

I spoke to two reps, neither of them had heard of or seen any notes of anyone tuning their Ridgelines with an APEX'i product. They both told me the same thing. In theory, the AFC-NEO is compatible but no testing has been done on the vehicle. It is compatibile with more cars than older models of air/fuel controllers and is also compatible with the vtec on the Ridgelines. They say it's a Ridgeline owner's best bet for such a product.

The price on the AFC-NEO looks to be in the neighborhood of $300-350$

It is not plug and play. Wiring/soldering and splicing is required. Instructions are included and their technical support is extremely helpful if you need to make a call for questions.

I hope someone else may find this information usefull.

It would be nice of JET to post a Dyno sheet of this HP Gain of the Ridgeline. I'm not saying there is no gain but some of us would like to see a stock dyno vs a jet chip dyno. So far there site only has a 95 Accord, 96 Civic & possible 98 Prelude (2.3 L Vtec).

Check with a member named alexander, I think he has some dyno numbers with a jet reflash.

I have no numbers, but my RL as gutless after Jet reflash as before. Save your money.

Did you do the JET reflash on your ECU?

Yes, I did. Actually it was done by JET itself.

And you saw no increased power or benefit? Does it seem the vtec kicks in sooner or anything?

Because I have used the AFC's in the past I would be much more likely to go that route. The thing is that the JET ECU is something that the average user can use and plug in and get some results.

The AFC is has two adjustable fuel adjustment maps for low and high throttle, switching points are also adjustable. On the V-AFC's or AFC Neo you also have an adjustable Vtec point. If you have never used or tuned a car before, you will need a scan tool that will tell you hopefully three things: Total timing advance, and Air/Fuel Ratio and possible knock levels (Hopefully knock counts but anything is better than nothing) If you can't see knock, watch timing values to see if timing is being taken away when you remove fuel. That is a general indication of noise being reported back to the computer. I would also highly suggest a wideband oxygen sensor be used to monitor things as they have much better resolution and should be a LOT more accurate than a narrowband oxygen sensor.

So, I'm waiting to find one for an inexpensive price, I would consider using a VAFC or AFC Neo as they really don't wear out.

As I said before, subjectively, I feel nothing. Maybe, if I had 2 RLs (unmodified and modified) to drive one right after the other I would feel a difference. Who knows?

Do keep in mind, from I was told the ONLY working option from APEX'i is the AFC-NEO which does monitor air/fuel correction and I believe monitors knock also. However, timing I don't believe is an option on this unit.

One use I've found for it: The Ridgeline shifts out of VTEC at WOT so the adjustable VTEC in/out points came in handy. By lowering the VTEC out point to the rpm to which the Ridgeline shifts to, the truck stays in VTEC at WOT
