Anyone Dyno'd JB3 2.0 & DCI's at high altitude? > 5000ft
Just got notification that my JB3 2.0, DCI's, BT & USB combo has cleared customs and should be arriving tomorrow
Now the thing is I live in Johannesburg South Africa at an altitude of 5700ft and am just wondering what sort of gains in wheel HP I could typically expect with just the JB3 & DCI's? I know its usually 60-80 HP at sea level but not sure what the effect of altitude will be? Bone stock dyno was 283 BHP & 303 lb/ft Also what 1/4 mile times can be expected with these mods at altitude, I've got a 6MT? The local guys seem to run around 13.8 stock Unfortunately 91RM (95RON) is the highest octane fuel available. However I can get my hands on some Torco octane booster, hopefully this should get me to 93RM? Has anyone tested 2.0, map5 at altitude higher than 5000ft using only 91, if so did you get any codes? I know a water meth injection kit will sort out all octane problems but unfortunately I'm gonna have to wait a while until I've got enough $'s |

OP, i am also in high elevation 4500 ft, i ran within a couple hp/tq as you bone stock, 91 octane as well, i gained only 20whp with map 3 on jb3 v1.4, and a whopping 80 rwtq, i dont know why only 20whp but a ton of tq added. Do not go above map 3 on only 91 octane at high elevation your car will most likely not like it and it is not worth the risk. In fact, my car seems to run smoother on map 1 so until i get meth/DP's im staying on map 1. Also i should be putting some catless DP's on in a week or so and plan on running 104 octane on map 8 at the track and dyno so i will post with what i get. im hoping for 350+rwhp and 400rwtq. And then im most likely going to purchase a procede to see exactly how it stacks up against JB. Good luck sir.

I am not sure you should run map 8 at 4,500 feet - even with race gas - could be a risk IMHO. Best to do a map5 log and send it to Terry for his comments. Do you have a custom map 1 tuned with terry's input ?? If yes - that is probably what u should run.

Will post an update once I've done a few data logs and fined tuned Map 1 of JB3 2.0 with Terry |

Question for OP
Hey I live in Utah too...at about 5,500 ft. but I'm running PROcede. I'm planning on taking the car to a dyno soon, but the closest dyno is in Salt Lake City which is at a lower altitude (roughly 4,500 ft).
I've got a question for you OP. Do you know if the track where your local guys are running 13.8 has some altitude compensation factor? I know for a fact that the track at SLC (rocky mountain raceway) is using the NHRA correction factors. It is posted on their website... I also know that since I have raced and beat some local diesel trucks that where supposed to be running faster times than my car. The only thing I have used for measuring the 1/4 mile times is my iPhone dynolicius. When I used to have my tuned 350Z I did compare the dynolicius numbers with my Cobbtuning accessport and they were really close... Anyway keep that in mind also. My best time so far was 13.92 sec @ 107MPH with a crappy 60' of 2.54 sec. That was bone stock E92 6MT, half tank of 91 octane gas, Stock RFT, on a private road at 5,500ft (GPS measured) I need to do some runs with the PROcede thought.... The whole reason I sold my Z was because forced inducted cars suffers less (power wise) from altitude than natural aspirated ones.... Yuji
