Thread: VE on a stock DE ECU questions

Hey all, before I begin...



Now that it's on. I've done enough research and got great advise from some of the forum members on here regarding a VE swap into a B14. What I understand is that there is no way to run a stock DE ECU without a tune, or in other words.. it will run, but very badly. My buddy seems to think it's all plug and play as long as you use DE components, like the DE MAF, intake, throttle body, injectors, dizzy and etc, even if the power gain is considerably lower it is doable. Essentially it would be a DE with valve lifters controlled by an MSD. Now let me help you understand why I would even consider swapping a VE and not necessarily look for full power. Our car is a Lemons/Chump racer, we blew the motor over the weekend () and we are now in need of a replacement. The car needs to be running by August and our budget is very limited. The easiest way to go about this is to drop in a roller rocker DE, but a used RR DE will have far more mileage and abuse on it than a JDM VE, so we're looking for something with longevity in mind.


So I want to know, is anyone out there actually running a VE on an OEM DE ECU without a tune or chip or board or whatever.

Many guys run their VE swaps on stock DE ECU's and dont damage the engine.

The only thing you need to change is the MAF and coolant temp sensor. These have to match the ECU.

yes,I ran my VE on all DE parts to get it running and get it to the dyno.
I thought it was running pretty decent until I saw the AFR and power results on the dyno.
I advanced the timing as much as possible and didnt switch the cams until tuned properly.

I would rather get a RR DE, you can find them with known millage. I would guess that the VEs are no longer Low millage as advertised.

that video is nuts

What set up do u have in the car now?

Currently it's mostly stock. We have a short ram intake, an OBX style header, an aftermarket 2" or 2.5" exhaust, with a punched through cat.

R u using a tuned ecu?

Negative. It's stock, hence why I'm asking if it can be run with a VE.

Use the DE injectors, DE MAF, and it'll run as good as it can.
