I've actually had this issue. I'll update and see if it goes away.

On a heart breaking Mustang Dyno. See below. Florida humidity/heat.

3.5 gallons of e85 mixed with a full tank of 93 octane
jb4 on map 2 (we think it maybe was still learning...see below)
ar *********
removed secondary filter pads
dinan exhaust

I switched it into Map 2 about 15 minutes before dyno. I did two spirited pulls, but I think it was still learning, as on the pulls you could see open/closed loop morphing and the a/f ratio leveling out.

I hit 527 torque on the last pull, but the power broke apart, and a got a hot engine warning so we instantly let out. Terry - what could be the reasoning here, as we only did 3 pulls? The fan we weere using wasnt huge, and the hood was closed, so potentially that is why. I have never seen this warning on the street.

Roger @ Pros Tuning, very smart guy btw, says his dyno reads 7-10% lower than the average dynojet. My buddies Supra which makes around 1,000 on the dot made 880 on this dyno on the same day.

475 / 502 on a mustang ; 508 / 537 on a dynojet (7% factor)

Im happy. Thanks Terry

Default LOG - 10-10-2015, 10:16 AM

Logging my car but something is off

I use the JB4 software on my tablet via USB and....

MAP1 on 91oct, my car hits 26psi

-Yesterday i added 4 gallons of E85 and put it on MAP7 as it also reached 26psi, cool...

BUT...

Then, i wanted to log and i check-marked the box that said "Ethanol Input" and after that, the car wouldnt make over 24psi

Any idea about that "Ethanol Input" selection?

On the JB4 mobile? You select that if running a flex fuel sensor. Doesn't effect anything on the tuning end. Yet.

Map 7 has a slightly variable target based on inlet temps. Logs attached look OK to me.

Considering my car was hitting max 26psi on MAP 1 and now only 24psi on MAP 7, could it be because i selected "ethanol input" on the mobile app? or did it not boost higher due to high IAT

Map 1 is additive. Map 7 is absolute. So the boost values don't mean much without the other variables.

Supports S55 JB4 cold/hot oil protection like the N55 ESeries JB4?

Quote:
JB4 has cold/hot oil protection built in. So expect stock like boost until oil temps are > 160 degrees. Same goes for oil temps > 280 degrees.

Yes, stays off below 160 degrees and tapers boost down starting at 270 degrees.

Dynojets measure WHP. Stock boost until oil is up to temp.

Just wondering about 430 whp stock, stock car has 431 at crank. That means with Map2 it makes ±600 hp at crank?

I've never seen a M3/M4 with 425HP/431PS. They are more like 460-490PS on german dynos.

Crank HP is a useless measure. You can't sit on top of an engine and drive it around.

I know, just want to interpret your dynos correct for our customers. In germany its common to display only crank hp - maybe because it "looks" better

Did you measure your 100-200km/h time? My car runs a 8.7s stock (Pbox corrected) and 8.5s uncorrected. That can't be 431PS. I'll hit the dyno soon. And - just to be correct - 490PS was the top of my range. It's more like 'up to' 490PS. Most of them have ~460PS.

Ich kenne zumindest keinen mit 431PS. Schau Dir Mal die ganzen Dynos an. War selber mit einem Kollegen drauf. 475PS :P. Habt ihr wieder die M4-Style Heckspoiler da? Meiner war leider von der Qualität nicht so gut ;-).

Hi,
When I attach JB4 to a right-hand drive, I cannot put it on because EWG harness is short.
I want an extension line for right-hand drives.

You can extend the two EWG wires if needed. I've not looked at an RHD EWG model myself but I imagine you could also locate the box on your passenger side to make more room within the harness.
