Thought this info and result might be useful to others looking to get a certain amount of power frmo a 16v.

11:1 wiseco, narrow port 4age (no porting)
IN 272/7.5mm lift
EX 272/7.5mm lift

Cam timing, Max lift IN@100/EX@98 as per club4ag.

Exhaust 4-1 w/2" system.
295cc injectors
Silvertop ITB, T3 inlet
VEMS 3.3 tuned on dyno.

Currently AlphaN from 0-8500rpm.
Ideally should be alphaN/Speed density blending.

First start:

Blue AE86 at the 15second mark is running vems.
Fully mapped, it is the car this thread was started for (since resprayed).

15seconds in, LOUD FAST BLUE AE86

Hey

Nice looking tests .

Question: why did you choose VEMS instead of Megasquirt ?
Haven't been really looking, but yours AE86 is first i see with VEMS, and so many are on MS.

thanks, regards

Sticky this one lets make a large thread out of it. One point post if its WHP or HP ?

My engine:

7 ribbed 40mm crank
81.5 mm toyota pistons
Ported bigport head
182CC injectors
260 in 9mm lift (Catcams: 7105137)
252 out 8.5mm lift (Catcams: 7105137)
Standard intake with open air filter
Standard ECU
Super 98 unleaded fuel

Stadnard header but cut at the 2-1 juntion to fit a 55mm diameter exhaust under axle.

This results into:

134.8 Rwhp and 150.4 NM on the wheels

On ideal situation I would be running 210CC injectors (which I have laying around) Engine is running a bit lean and I have a power distortion at 7400 rpm

VEMS and OMEX 600 ecu's are really nice. And you don't have to build em. They are used in kitcar build etc

Builiding is not that big issue, beside you can buy it assembled. That cost more but MS is beside VEMS (as much as i know) cheapest ECU. OMEX 600 is near, but still more expensive. I am aware of much better and more expensive standalone ECU's (MOTEC, NIRA...) but i intentionally asked about VEMS and MS since these are (beside carbs ) cheapest options.

So, at least from me, question stay: why VEMS and not MS ?

PhatBob lives near me and answered all my questions about EMS.
No tuner, not other ecu manufacturer ever answered questions on how ecus work, or whether it would work as part of a plug and play system.
Something I was keen to setup for Irish AE86 owners.

I asked Bob try out a plug and play loom on vems several years ago.
" alt="[Image: AEU86 AE86 - Tuned
It was successful but showed problems in stock AE86 wiring.
Helped me understand the benefits of crank trigger, good earths, shielding etc
after looking at signals on a scope trace.

I am happy to buy from Bob as hes honest and the technology is proven.
I like how VEMS Maps the engine VE, showing you what its doing.

Lots of reasons, but Im at work and dont have time to type
VEMS works!

150.4NM = 110 ft lb yes?

@20% transmission loss

~169.7hp @ flywheel
~137ftlb TQ @ flywheel


@25% transmission loss
~180hp @ flywheel
~146ftlb TQ @ flywheel
I doubt without awesome headwork, blueprint and balance you will see ~140ft lb TQ!

So 169hp/137tq @ flywheel seems right Nice numbers

HP in dyno posted is est flywheel hp.
ECU was tuned on the dyno!

Very good results mates!!!
More more tuning and dyno!!!
