Tuning the 8HP Swap with HTG!

[@markburley9443]

honestly this is the best explaination I have seen for any tuning on the HTG GCU, finally an explanation to why my tyres chirp going from fifth to fourth!

[@FredAllenBurge]

Love it, I'm almost there with my 240+LS+boost+8hp70, just a few steps left!

[@davidwitcher5443]

Any updates? What did the transmission come out of, adapter and controller did you use?

[@FredAllenBurge]

@@davidwitcher5443 almost to first test drive, sub to my channel for updates if ya like.

[@davidwitcher5443]

@@FredAllenBurge Will do. Thanks!

[@widfo_moto7345]

You guys need a vid like with the DCT haha

[@sr20dett1000]

Can you use a bmw OEM shifter? Good work but turbolamik tcu makes a very street friendly swap using BMW f10 shifter I believe. Downside is they are in Australia.

[@SeemsLegitGarage]

you can use a huge variety of BMW shifters

[@rayjones3473]

Why not turbo lamik?

[@imSchwaggy]

is there an 6hp/8hp kit for the foxbody 5.0? im mostlikely gonna grab a 5.0 swapped e36 soon and i want to eventually auto it.

How do you guys set the tune for hi load without damaging the trans? For example when tuning on the dyno for max power?

[@SeemsLegitGarage]

The closed loop control sees slip and adds duty cycle

[@mrfiasco7941]

What wtg was this pushing, I heard you say 700whp but what about tq. How's the trans holding up? Cheers

[@truecapacityfitness1611]

I’m also here to find out how the 45 is holding up! 👍🏼

[@levicharles4499]

At 8:22 it looks like their shift rpm is 7k, so I’d like to assume (best I can do for now) based on that and the fact that the N54 is under square; meaning it makes peak torque relatively low in the rpm range (between 4.5k and 5k rpm and peak power between 5.8k and 6k rpm stock) that they may be making peak power around those rpm ranges still. We can transpose the formula (Torque x RPM) / 5252 = Horsepower ,and substitute those power and rpm values into the equation. (Will be using the lower peak power rpm value for a higher torque output) We will get something along the lines of. (Horsepower x 5252) / RPM = Torque (700 x 5252) / 5800 = 633wtq which This can mean either they are making a bit over 700whp at 5800rpm or they are making 700whp earlier than 5800rpm Hope that helps

[@SeemsLegitGarage]

Torque is around 625, I don't really want anymore down low it just blows the tires off on corner exit

[@levicharles4499]

I too would like to know how it’s holding up as I would like to make considerably less hp 550whp at 5500rpm which would mean I’d be making 525wtq at that rpm. Would be great to put my mind at ease know that these 45’s can comfortably hold 2x their stock tq rating

[@SeemsLegitGarage]

@@levicharles4499 no issues yet!

[@jdmheartperformance3580]

Still runnung the box? How is it going?

[@SeemsLegitGarage]

@@jdmheartperformance3580 all good, going to a LS3 and a dodge 8hp70 this winter :)

[@alexgonzalez7395]

Kinda dumb question but does it shift on it own as well.

[@SeemsLegitGarage]

yes it has auto mode you can program to shift automatically as well

[@davidwitcher5443]

Does the transmission need engine defuel?

[@SeemsLegitGarage]

no

[@MattyMattsBavarianBuilds]

what rear diff ratio are you using with the 8hp?

[@SeemsLegitGarage]

3.27

[@Breakmywalletmedia]

@@SeemsLegitGarage think the M3 3.15 will work with it? Also how is it from a dig?

[@SeemsLegitGarage]

@@Breakmywalletmedia Awesome from a dig using the trans brake or clutch dump. 3.15 is perfect.

[@DK-421]

@@SeemsLegitGarage would 3.38 gearing be too aggressive with an 8HP70 in an e39 540i?

[@SeemsLegitGarage]

@@DK-421 not terrible but deff aggressive

[@Vgk36]

Hey guys what rough estimate would I be looking at all in on a 8hp for 2003 e46 sedan. Including driveshaft and literally anything else you can think of. Thank you guys for all your hard work putting content out !🤘 About $4500 but will the paddle setup work with a factory e46 steering wheel. I want to keep all the radio and fimctions plus airbag 🤘 hello 👍

[@SeemsLegitGarage]

Hi, this is totally doable. The car wont be affected at all. I think 5-6k is doable if you are DIY
