ECM Modification By FeatherFoots Friend

I would be interested in the 4 setting ECM reprogramming option.

I'm interested. For instance, I like the shift behavior of normal mode, but the added timing of Power mode. More with less downshifting would be nice.

Now I think one thing needs to be clarified, and no-one has mentioned it yet. That 30hp claim was on a 350cid GM...a 5.7l pushrod engine. Much bigger than ours, but lower tech. I highly doubt gains of 30hp will be seen on our little 3.5l engine. Maybe closer to 20 if I were to speculate. $350 is still a bargain for that.

I had a custom 4way chip in my Typhoon. Pretty cool to have options, but after a while you will most likely settle on just one. It's great having seat wime with all of them though, like we do with Power mode.

Actually the 5.7L engine got closer to 60 HP.

The 30 HP quoted was the estimate from the manufacturer for the 3.5L V6.

I would be interested in a 2nd chip programmed for performance. I don’t know what the cost would be for that. Either that or a 2 setting ECM reprogramming option, one that goes from stock to performance. I am still under warranty and with the way Isuzu is being I don’t want to take any chances. I am honestly hesitant about changing my own oil. I do change it because I like knowing the job is done properly and with quality products but if I ever have problems I still wonder if they will try to deny me.

So John what is the next step to getting this chip into reality?

Just be patient. They said it would be after the first of the year before they could fit it in.

Cool, Thanks for the heads up.

Talk is cheap. Show me the dyno results, and I'll show you the $350.

If I recall the rear wheel HP of a Stock VX is about 166 at the top of it power band. (About 3500 RPM)

It's possible that I have the original dyno files on my Computer at my office. I'll see if I can dig them up.

Talked with the chip guy last week. He's helping John jr re-build his motor and said that the chip/programmer will have the ability to program/unprogram/re-program as we discussed earlier.

He has 4 or 5 different autos to program and restated that baring any thing funky in the ECU he hopes to have the "devvice" ready for sale by February.

John,

Do you need a head count to "encourage" production? I'm in.

Reply:
SC DYNO RESULTS AT TOP OF POWER BAND ( About 3500): Indicated 237.4 HP. When Xmission shifts HP drops off to about 187. which results in about a 20 HP increase at that & higher RPMs


My Vx was the first one to have the supercharger installed. Aside from installation of 5 lb pulley. HP & torque figures shold be very close.

DYNO RESULTS

Before SC install- HP-165.3-RPM 5025- MPH 103
After SC install- HP-212.8-RPM 5025- MPH 103

TORQUE
Before SC install- 179.8- RPM 4106-MPH 85
After SC install- 235.6- RPM 4106-MPH 85

I checked my files and here is what I have:

Anita's Baseline and after exhaust installation

Boiled down from all of the data.

Dragon Bob's data - both raw and boiled down The raw file, when converted to excel format is about 3000 rows long and 12 columns wide. This data is baseline, after S/C, then after exhaust with the S/C.

This may be why I got run off from there. At the lower RPM's the S/C added 40 HP and the exhaust added 85 more.

The files are mixed Excel and Word Pad. I'm not going to paste them here. If someone wants to do that I'll send them to you.

P.S. Bob's numbers are correct as I remember.

WHAT??? Where do I sign up for THAT exhaust?!? Is that 5hp more?

[FeatherFoot]

actually it is more as you increase in rpm for a while, at 3000 RPM the exhaust added 92 HP to the S/C'd engine.

That's why I want someone else to post the charts etc.
