LAP3 ECU and TCU Review

[zdunkle7]

You are running full E85?! Sweet. I run e50. Mine is a taper fuel bias. I probably try too hard.

So like 80-70-60 or what? I’m curious lol

Starts at 70 and tapers to 50. That is my usual one. I do change it up (depending E content and Outside Weather.) I use trims as my guide. Happy to help.

Based on the non responses, I’m guessing those cars with the 1.5 and 2.5 aren’t still running….

2.5+ here. 15000 miles still running strong. E30-E60

Thanks so I have been talking with Davis pretty extensively with lap3. Is great at responding promptly, but I’m looking for hands on experience from customers. Did you have the 1.5 or JB4 previously? Regardless, how is the 2.5 and any downsides? Thanks!

 

[44pirate]

Always been Lap3 2.5, no downside runs great.

 

[SnowyGT2]

I had Stage 2.5 for almost two years, no issues, car felt great. Using CPI with approx E60.

I traded in the vehicle. Still have the Lap3 Stage 2.5 ECU for sale if interested

 

[winjury]

I’d love to hear the details on it. No idea how to send private messages on here.

is there a difference from 2018 and 2019 lap3 2.5 tune?

 

[zdunkle7]

I’m running JB4 on Map5, and my ECU & TCU are both Burger Motorsports Backend flash tunes, E85 IGN19 BEF & TCU ALPHA. Running full E85 via Charge Pipe Injection. Been running this setup for over 6 months.

Also, if anyone has any exhaust mods they are selling, hit me up, I’d be interested in buying! I’ve got a ‘21 G70 3.3T RWD, primarily looking for primaries, and catbacks that I could modify to fit the G70. But if anyone is selling anything else for a good deal, I’d most likely be interested.

everything you have is exactly what i am running (then plus exhaust and intakes) but i cant go over e60 i get misfires. I usually keep it around e50 and it runs like a champ.

I’ve got drop-ins, hot side charge pipe, ewg wires, bov, boost launch controller, ebc slotted rotors & redstuff pads, and toyo r888r’s on the rear as well. I really think it’s just car-by-car basis with how much E85 they run. Apparently the post-facelift G70’s have a better chance at running full E, but my pre-facelift runs it with no problems… weird isn’t it.

As Terry will tell you. No benefit with his BEF above E60 anyway. So I also run E50ish as well.

I totally understand if the car can’t run full E85 and you choose to run E50, but I’d much rather use full E85, for two main reasons; only have to use one gas pump, 93 is much more expensive than E near me, and there’s no benefit for me to add 93 in.

100% agree. I don’t even have an E station in my state. So have to outsource it. If I had I pump- I would do that same as you. (For me it’s like double price of gas)

Ya none of those additional items would be why you can run full e85. I know my year had issues with HPFP dumping, I may just replace mine with a better one just due to at because it’s not mileage (52,000). I agree with your reasons why you use e85. My 2 of my other vehicles use full e85 also and that’s pretty much my reasoning. lol. In Florida pumps are everywhere.

 

[44pirate]

With my setup I was able to run 10gals e85 the rest 93octane. It ran great but 8mpg sucked.

 

[winjury]

8mpg? I have never seen it that low. If I’m just in the city driving and in sport mode it’ll be around 16, but no lower. Highway will usually be 22
