LS1 brains for you L98 or LT1 - EFI connection

You guys seen this yet?

EFI Connection has figured out how to implant a LS crank/cam sensor into your LT or L98 (TPI) motor to run it on a full coil over plug LS1 computer - even DBW if desired.

THis is SOOOO cool, because it brings the OBD I guys back to the table with something to share.

I'm looking into it for our 1986 Corvette. It won't give you more hp per-say, but it will allow total tuning down the road which sorely lacks on the L98 E-prom systems.

Oh...and they are also setting this up for ANY old school Chevy big or small block. This is going to be devastating to the aftermarket (FAST...etc) EFI guys.

Whats up with the link it a photo of your drive shaft?

Link fixed...

They have had it out for a year or so now. If my plan continues forth the way I have it now, I'll control my LT with an LS PCM using their parts.

The Gen 6 BB is easy to convert using all GM parts. Use the 24x crank reluctor wheel and sensor from a 98-00 P30 Van 7.4 vortec and either the 8.1 timing gear and cam sensor (need to weld top of 8.1 timing cover to botton of vortec cover check the ram jet motor on their site) or use the vortec dist as a cam sensor.

I'm currently working on an oil pan conversion to use the gen 6 pan and timing cover on a Mark 4 block to take advantage of this ability for old and aftermarket BBCs.

Cool stuff. Their 24x wheel for the SBC would be good choice with an aftermarket EFI system, no hokey dual sync dist.

Can you run a double roller timing chain on the Gen 6 BB?

Can you run a double roller timing chain on the Gen 6 BB?

Rollmaster makes one, but it will not work on the new bowtie blocks. The chain will not clear the protrusion of the water jacket. Works fine on production blocks like the 454s and 502s

I have not yet tested to check fit with the reluctor.

The GM single roller is a nice piece, steel gears and a German made chain. Its good for any hydraulic roller setup and probably most streetable solid rollers as well.

This is easy and can be done by yourself with out anything fancy.
There are several people making 24x crank triggers that have the same factory type hall effect sensors, GM made a Cam sync for the big block vortech engines that is a drop in where the distributor was, it will drive the oil pump and provide a hall cam signal.

The only other thing you would need is the $600 Hp tuners program to scan and tune it with.

A LS computer setup for 24x signal

A harness for the engine.

Don't worry, this isn't a huge replacement for alot of the stand alone ECUs out there FAST, ACCEL, Big Stuff 3 ect... the factory GM stuff is actually harder to tune then the aftermarket stuff, way more tables, more modifiers, no wideband ect..

But the LS computer is a bad ass piece for a stock computer for sure, I ahve been tuning with them for the last 6 years and for a stock tuning computer they are better than most.

Man..I'd like to see the part numbers for those oem and or conversion parts. It would be intereting to add it all up both ways.

The biggest issue that this product takes care of is for people like me which have LT1s and want to run boost. You can't sense boost with the LT1 PCM and you have to deal with the opti.

Any 24x crank trigger hall effect sensor and wheel will work. I know Big Stuff3 makes one. There are a ton of other people making them too. Look up the Vortech cam sync from the newer 496 for the cam sync, it is also hall effect and drop in instead of the regular distributor. With these two and the right adjustment on the crank trigger the stock ECU will not know the difference.
